Location, Location, Location

I thought I’d talk about the difference in my yard and my neighbor’s across town. While we share a great many birds, of course…we each also have birds the other seldom, if ever, sees in their yard.

Case in point, I’ve never seen Bluebirds, they’ve never had Rosy-Finches. I get hundreds of red-winged blackbirds; they get a few. Eurasian Collared Doves don’t seem to be a problem for them, but I get hundreds of them, too. I’ve never seen a Towhee here…but they have several; even an Eastern Towhee visited them! While I regularly have half a dozen Blue Jays, a few Scrub Jays and once a single Steller’s…they get those plus dozens and dozens of Pinyon Jays that I've never seen here. They've never had a Rose-breasted Grosbeak, but I get them every year. Once, I believe they even had a Snipe in their yard! I could go on about the difference in birds. And while I am plagued by squirrels, can count a dozen at about any time and can hardly keep them from destroying feeders…they don’t have a problem with them. We both get bears, though my Akbash keeps them out of my yard; same goes for deer.

Like my friends, it was where I bought that got me into birding. Mine, like theirs, is a very birdy yard. Because of that, and also much like them, I’ve started feeding, watching and counting birds, as well as continued to add more shrubs and trees to increase the ‘birdiness’. I’ve discovered old, native, species plants work best; beautiful cultivars are bred for neither nectar nor seed…just beauty or perfume.

I bought the house where I live now because of the large lot (it’s four, long, town lots: 100 x 150’ or about 1/3 acre). I believe it’s on one of the prettiest streets in town; due to the huge willows, old cottonwoods, and assorted evergreens that surround the area and follow the river through town. And many people have planted different kinds of apple trees…most of them quite old by now. The river, a creek much of the time, flows about 100’ from the back of my house; when it’s high, I can hear it. The rectangular lot has an open back-yard with beautiful, southern exposure.

In spite of all the trees around the perimeter, my lot is actually quite open. While I do conduct what I call 'Turf Wars', there is a good expanse of lawn in the front and back of the house. The house is toward the front; leaving a good-sized open area out back. When I arrived, there was one small Blue Spruce, several old apples (I’ve removed two), a couple lilac, some wild plum, chokecherry, Virginia creeper and a large patch of raspberries. Two, rather small, old Cherry trees are back there, too. Near where I cut down a huge and rather nasty apple tree, I planted a smaller and not so dominating crab apple. I specifically looked for one with 'persistant fruit'; fruit that hangs on all winter rather than making a mess under the tree. When apples freeze and thaw, they make great food for deep winter feeding. This tree has apples not much bigger than coffee-beans; smaller even then the cherries. I love it, as do the birds.

I’ve added a ‘screen’ around the propane tank that sits towards the center in the back of the lot: New Mexican Privet, Low-grow Sumac and Cotoneaster; all of which offer berries. In the corner of the lot is a huge mass of the creeper; climbing where the back and west fence meet. Two more Cotoneaster and a River Birch were planted ten feet or so in front of the two, large chokecherries against the west fence, just up from the 15’ raspberry patch. I hope they make quite a nice thicket; a banquet for birds. Also along that same fence, about 30’ from the house and where the Blue Spruce and apple trees live, I also planted a (thornless) Hawthorn and an Elderberry Bush that’s gotten nearly as big as the huge chokecherry bushes.

Closer to the front of the yard, past the old apple trees next to that Hawthorn, are several Golden Current. At each front corner, on the street-side of my property…there are huge trees. These trees line both sides of the street and are mostly cottonwoods and willows. The bears love to sleep in them. More Virginia creeper lines the lower front fence and a Box Elder grows in the corner, under the bigger trees. I planted some Honeysuckle on the East corner, near the front gate. It offers berries, too, though not as many as the creeper.

Back down the Eastern side of the yard, there are wild plums and on the other side; several more old apple-trees. Past those trees, and all around me, I see more giant cottonwoods, aspen and evergreens, as well as big willows, and more chokecherry thickets and large Maples. Along that fence, near the center of the yard, I’ve planted more Elderberry, Mock Orange, Serviceberry, a cone-shaped little juniper. Curving into the yard behind five or six 50-year old Peonies are now Sand Plums, Mugo Pine, and several Viburnum types. Behind those and towards the very back I planted three, old-variety, own-root roses like the one I had in Denver. It was a huge thing that climbed up over the garage, had clusters of sweet, pink flowers nearly all year…and is thornless! Those three are already about 5’ high; I love that they need absolutely no fussing over. In a couple years they should drape about 25’ of fence. Those are for me, not so much the birds!

Along the back, perhaps 10’ in front of the fence, I’ve planted some goodies I brought down off the mountain where I lived; a foot-tall spruce, an 18” Ponderosa Pine, some Kinnickinnic and Creeping Mahonia. Next to that I’ve added a regular Sumac, and an odd, spiny Cotoneaster. Behind this ‘screen’ are the rather casual compost heap and a brush pile. There is another brush pile behind the two cherries on the other side of the yard. And that’s the loop.

Here and there, especially in the walkway between the house and garage, I’ve planted wild grasses, many native flowers and a couple more Mugo pines. On the little hill where the water-fall starts, I’ve planted several very low junipers, yet another mugo, a Coralberry, two Cranberry cotoneaster, some native, red ‘Hummingbird Flower’ and a sweet clump of what I know of as Sea Oats. Along the water fall is Creeping Jenny, more creeping, purple mahonia (it berries) and other low-growing goodies that I hope fill in and hide the liner. I can see the whole back yard from my big, new kitchen window; even the fish in the pond.

Like my friends across town, I’m protected from winds by both the hill down the street and all the huge trees. My yard stays quite calm most of the time. I’d like to get a few more shrubs, but leave the openness of the yard. Most plants that I buy these days are for bird-food or shelter…and, if possible, 4-season beauty. I like hardy, xeric stuff that I don’t have to mess with. I am an organic gardener; with the water-table less than 3’ below me and feeding birds as I do…how could I be otherwise? I even worry about neighbors spraying as ‘drift’ can kill pond fishes. While I consider the little pond a bird-feeder (there are lots of Kingfishers around), I don’t need a fish kill, too.

Most of my feeders are away from trees; an attempt to keep squirrels off of them. I offer different food in different feeders and don’t offer much mixed seed. I find it a waste of both money and seed; common millet is a filler-seed that most birds don’t especially like. Most of my feeders have Black Oil Sunflower Seed, some have Safflower Seed (Evening, Black-headed and Rose-breasted Grosbeaks LOVE it) and every morning I offer unsalted, in-the-shell peanuts on a flat-bed feeder, along with a cup of large dog kibble for the jays and magpies. Sometimes I also dump leftover bakery goods, cooked pasta and a bit of meat scraps. A bunch of grapes brought in Robins.

Smaller seed on an open feeder would attract flying pigs that decimate the contents in minutes. I also offer home-made suet during the winter and orange halves during the spring along with a small cup of grape jelly. Everything from Grackes and black birds to uninvited doves and starlings mob the suet; but if I can possibly avoid them, woodpeckers, chickadees and the flickers love suet too. Black-headed Grosbeaks, Summer Tanagers and Bullock’s Orioles love both the oranges and the grape jelly. Once, a Baltimore Oriole did, too!

Lastly, several feeders are for small finches only. In those feeders I do use a mix. It’s called Finches Feast and is an equal blend of black thistle, canary seed and sunflower-heart chips. The mix works in any finch feeder and is half the price of the Nyger seed sold as thistle for finches. Oh, and in the spring, when I put out nectar feeders for the hummers, I also make sure all the holes are enlarged enough to accommodate both Orioles and Tanagers, too. They love nectar.

Perhaps this spring, I will offer one feeder (set for only light-weight birds) with White Proso Millet. I understand common millet and milo (sourghum) (cheap birdseed fillers) attract mostly doves and sparrows; White Proso is also favored by finches, juncos, siskins, sparrows, titmice, towhees, woodpeckers and…buntings! I love the Lazuli and Indigos that come through.

Polly Wren who lives just outside of town, amid fields of grazing cattle, nestled amongst the tall trees that follow the river. Their quite different habitat is wilder and thicker than mine, with many trees. Many, if not all, of their feeders hang from or are built beneath the overhand of trees. Their yard is beautiful, and quite different from mine. She writes:

"Our personal property consists of 2.5 acres. Paul's parents own the adjacent 4 acres (all running along the stream) so the family parcel is 6 acres. We have a stream about 100 ft. from the house with a completely natural screening of old cottonwoods, choke cherry, box elder and other shrubby stuff between the house and stream. This provides us with much needed protection from the winds...While the winds might be howling all around us...our yard most times is relatively calm. We are about 7,000 ft. elevation.

In the actual 3/4 acre that we call the yard...we have natural grass, and have planted lilac, aspen, Newport plum, cherry, crab apple, one elm tree, purple and mountain ash, weeping willow...white fir, bristle cone pine and blue spruce...in other words: it's a jungle out there.

The strange thing is we did not set out to make our yard "bird friendly"...we were not birders when we built the place 16 years ago. We became birders because of the birds that would "just show up", and then we have sort of discovered some things along the way.

Deer tend to be a problem here...so we have deer fencing around the base of the trees...this we noticed protects the trees from the deer but is a pain to weed...so we don't...by simply being a little lazy we created great little hiding places for the birds at the base of our conifers and shade trees. We are also pretty lazy about cleaning the brush completely off the property...hence we discovered birds like those "brush piles"...more shelter.

For the most part I think we just really sort of lucked out by building in a place that was already "birdy"

As far as seed goes I discovered these great seed blocks at of all places Safeway. Birdola brand, Deck and Patio blocks...peanut hearts, sunflower chips; no hulls. Nuthatches, Pinyon Jays, Blue Jay, Chickadees, and Goldfinches all love it. Next is plain Black Oil Sunflower Seed, and suet blocks. Beverly turned us on to Purina Mills Wild Bird Chow called Finches Feast. That is about it.

We tend to take the feeders down around the first to middle of June to keep the bears from habituating themselves to them. We put them back up around the 1st of November.

Also as to feed, this spring was the first time we put up oranges around the yard and it really paid off with more that 2 dozen Western Tanagers and over a dozen Bullock's Orioles coming in daily (more than we have ever had before).

Over the years we have racked up quite a nice little yard list of 116 species which does contain some real rarities...again I think this is due to location more than anything else...
"

So; theirs is a forest, mine is more open. While I leave brushy, tall grass around the edges, they leave their yard wild, and mow paths through it. They've planted many large trees, I plant smaller trees and islands of shrubbery. I'm guessing habitat makes all the difference...and it's all good. One thing is for sure, their photography is so much better than mine! All pictures here, are theirs. Thank you two, so much!

Every Litter-bit Hurts

Awhile ago Birdwatcher’s Digest published a piece regarding the surgery necessary on a California condor chick. It seems it was full of garbage people leave where they drop it. That just galls me; hiking anywhere and finding bottle caps, broken glass, pens, lighters, etc. Trash is more than dangerous.

From this single condor chick was removed:
  • 4 bottle caps and a screw top,
  • 3 electrical fittings,
  • 5 washers,
  • 13 22-caliber shell-casings,
  • 1 38-caliber shell-casing,
  • a shotgun-shell,
  • several pieces of plastic bags,
  • about a quarter cup of broken glass,
  • a similar amount of broken plastic,
  • a few small pieces of fabric,
  • 4 small stones,
  • a metal bracket,
  • a piece of wire,
  • and a few small pieces of rubber.

Read the full article here.

Trash tossed or absent-mindedly left behind is more than just unsightly. Trash, especially plastic, can entrap or suffocate mammals, birds, and fish. Small pieces can look like food and be ingested causing harm or death to the animal that eats it. Thousands of birds, fish, turtles and mammals die each year from entanglement in debris. Common items like six-pack rings, fishing line and strapping bands are mistaken for food. Numerous species ingest plastic, which causes them to feel full and die of starvation or poisoning.

Remains of an adult Albatross with gut full of plastic (below). Notice the wide variety of bottle caps in this one. With smaller animals, more damage is done by smaller pieces. The plastic goes down the gullet quite easily. But since it is not digested, as in the original plan for all life, it gets stuck before exiting the stomach. There it sits to block the entry and digestion of legitimate food. Even the tiniest of pieces can cause blockages.


Probably the most disgusting thing I’ve read in some time is so absolutely shocking I can’t even talk. Go read it and let me know what you think. Good lord, if this is how our oceans look, imagine what our skies are going to be before too long. Sheeshhhhhhhhhhhhhhhhh... Who knew?

Is It Safe to Feed the Birds?

I run into this question a lot. Either as “I don’t believe in feeding birds”…for reasons about interfering with habitat and/or migration, I think. Or, that with the threat of Bird Flu hanging over us; why court trouble? I’ll respond to this question in three parts: habitat, migration and human safety.

Let me start by saying good bird habitat is shrinking right along with all habitat. We think of forest as habitat and that it is only being depleted in tropical countries. However, considering that we are loosing hundreds of acres of forest and croplands per state, per day, to development…and add to that global warming which is creating havoc with weather and temperature which in turn creates havoc with what grows where…and to that add the results of pollution and poisoning of waterways, bodies of water and the earth and air that all living things depend upon…and you will understand why birds are declining. It is for that simple reason that I feed birds.

So many birds migrate; some traveling thousands of miles, sometimes over multiple continents; to get to breeding areas. Considering that they must find food and rest along the way…I rather enjoy the idea that I am helping the birds by feeding them. I keep my yard planted with native plants; it has been discovered native (natural) plants have more nutrition (nectar) than do those bred for beauty. I use no herbicides or insecticides and use natural fertilizers. I keep birdbaths and small ponds clean and free of ice, and I offer seed, suet, and nectar and sometimes nuts and fruit. At the height of summer, I slow down on the free meals and at the height of winter I increase the number of feeders times three or more. And I have a view far more interesting than the television set.

In my mind, we owe birds for the damage we’ve done removing their habitat; for ruining their water and depleting their natural foodstuffs. Birds are not just pretty beings; we need them for so much more than just entertainment. Birds are necessary for seed distribution and pollination; insect and invertebrate control; mouse and other such pest control, scavenging and keeping forests, rivers and parks clean. I think we owe ‘em. (and no, they won’t suffer if you go on vacation and don’t feed them for a few weeks).

Regarding the idea that feeding wild birds will cause them to stop migrating is an urban myth. Birds begin and quit migrating when weather changes. It has been discovered birds are moving migration sites some 40 miles north…due to climate change. That would be why we have some birds staying in Florida or along the Gulf of Mexico instead of moving for the winter to Central or South America. Nor will feeding wild birds make them lazy.

As far as bird flu goes…while it has been confirmed that wild birds are in part responsible for the spread of bird flu, it is from association with kept birds that humans become infected. Cornell Lab of Ornithology, the Centers for Disease Control and Prevention, and the Audubon Society, all agree it is quite safe to feed wild birds.

I feed wild birds. I am comfortable that not everybody wants to do so. I love it that some folks ensure their yards include bird-friendly plants; plants that feed the birds and offer them places to rest or nest. That’s plenty good enough for me! Just watch those chemical poisons, please; and keep in mind it travels by wind and water…ever deeper and right into our waterways. Heard about dead zone in the Gulf of Mexico? Chemical fertilizer is considered the prime cause of dead zones around the world…it’s not something that only happens somewhere else. And it starts in each of our own backyards.

Cornell offers a wealth of information regarding birds and feeding birds, and Audubon includes similar information, as well as a really good FAQ page.

Feeding waterfowl seems to be a whole different ballgame, however. Most people feed bread and cheap bread at that. Bread, pop-corn, chips; all have little to no nutritional value. It also encourages the congregation of ducks to the point that water and shores and walkways become fouled with feces. Bread in water encourages algae, which choke out the life in water when overabundant. You’ve seen it happen. Please, don’t feed wild ducks!

Seeing Birds: A Yellow Warbler

Slowly I’m learning how to see birds. More and more I’m using habitat to tell me when I’m looking at a ‘different’ bird. This morning I looked out across my yard and saw a bright yellow spot moving around near the cattle-gate I use for access from the wide, willow-lined alley that leads to the river. The small bird was behaving more like a fly-catcher than one of the pretty little Goldfinches that frequent my sunflower feeders; sitting on a gate-rung, sallying up and out to catch an insect and returning to the same place. It was feeding low to the ground, but obviously fly-catching.

Grabbing my binoculars I could see it was probably a female Yellow Warbler (males, I’ve read, forage higher up than ground-level); I’d seen the pretty, belly-streaked males earlier in the season…but hadn’t actually noticed Warblers for several weeks.

I joined Cornell Lab’s ‘The Birds of North America…Online’ and have reading voraciously about all kinds of birds. This Yellow Warbler is a little ‘change artist’; it looks quite different depending on where they breed. The migratory Yellow Warbler common in North America has a yellow head; the non-migratory group of Mexico has the chestnut crown-patch pictured in this photo by Satish Nair (which one a calendar contest at the Galapagos Conservancy.) The other non-migratory group, which breeds in the tropics, has an all-chestnut colored head. Geographic variation in plumage is rather marked between groups, but generally more subtle within groups; but just to keep it fun, overlap in almost every character cited may be found in one population or another within each group! Ahhhhhhhhhh…birds! It’s all fascinating…for more information, I suggest you subscribe to Cornell’s website; the information is awesome.

Reading on, I suppose it is no surprise I have the Warbler’s here…apparently Brown-headed Cowbirds are especially fond of parasitic behavior towards them; laying their eggs in the Warbler’s nest. I had dozens of Brown-headed Cowbirds here earlier. The Yellow Warbler is apparently one of the few birds that can recognize its own eggs and sometimes knows when one is ‘different’. That Cowbird egg, while similarly spotted, is a lot bigger. This smart little Warbler has an interesting strategy for dealing with them, when they do notice ‘em; they merely build a new floor right over the Cowbird egg and raise the whole nest up…sort of encasing the parasite’s egg under the ‘false floor’, so that it would never hatch. They lay a new clutch and start over; one level up. Some Yellow Warbler nests become quite tall as a result of this behavior! Wild, huh?

Still, there can be dire results resisting the parasites; here is an astonishing article: "Mafia Cowbirds: Do they muscle birds that don't play ball?" by Susan Milius

No More Wall

I just discovered David Sibley’s Blog (try to keep in mind I’m new!)…and while I’ve been using his guides for some time I was absolutely tickled to find on his site a different angle regarding Chertoff and that ridiculous wall he’s having built along our boarders. I’d like to quote Mr. Sibley as there is no way I would come up with his eloquent message:

More on Texas Border Wall

Prompted by some good discussion I've read on TexBirds and elsewhere: I want to stress the point
that the danger to birds is not so much the height of the wall, but more the wide swath of habitat
that would be cleared for the wall and service roads. Chachalacas, Pygmy Owls, Green Jays, etc
will fly over a wall, but they're less likely to cross 100 yards of barren gravel. This project might as
well be a 4-lane highway.So let's try to take immigration completely out of the picture for a
moment and imagine that, instead of a wall, the federal government was proposing to build a 4-lane
expressway along the river from Brownsville to Laredo. Wouldn't there be a unified grassroots
uprising against it? What if they revealed that it would cut right through parts of the LRGV Wildlife
Corridor, which has been so carefully patched together and cultivated over the last 20+ years?
And what if there would be no exit or overpass anywhere near the Sabal Palm sanctuary and
other sites, effectively cutting those places off from the existing road system? And, on top of all
that, what if they announced that, in order to speed construction, all environmental review
would be waived? Wouldn't we all be outraged? People may feel conflicted or uncommitted
about the border wall because it is tangled up in hot-button issues of immigration and National
Security. But those issues are irrelevant to the birds. The reality is that the wall (like an expresswa) would be catastrophic for birds and birding in the valley (and what's bad for birding is generally bad for the birds), and we need to speak out to demand that those concerns be addressed. Congress allowed all this to happen, and they can change it, but they need to hear from lots of us. See: No Border Wall for more information.

I have written my state representative and hope you do so as well! If you live in the US, you can find the address of your representative by clicking here. Regarding this post…I have set aside the issue if keeping people in or out of a walled country and am ONLY discussing the matter of what a wall does to wildlife. Thank you.

I have made use of the above website’s banner and Silbey’s writing. I hope this cause and my quotations will mitigate any improprieties. Thanks again.
