Fletcher Wildlife Garden is the awesomest place
May 26th, 2009

Swallows are some of the most beautiful birds in North America.
You've probably seen them before: flocks of them circle over ponds and rivers
in the evening, hawking for insects, moving too fast to pick out any detail.
Swallows are so graceful and streamlined that they can stay aloft for hours,
never stopping to perch. Usually, the only way to get a good look at them is
to catch them nesting.
Which is why Fletcher Wildlife Garden is the awesomest place. It's got a pond
surrounded by very successful Tree Swallow nest boxes. They're busily setting
up now and will be raising families in the month to come.

The Glare
May 24th, 2009
I took several pictures of this grackle, and this one, colorwise, was not the
best. But I just love the look he's giving me. "Do you
mind, lady?"
(
Bird geekage within )
Orioles continue to pose prettily for me. Most of the orioles at Mud Lake are
now breeders, not migrants. I can tell because orioles have
dialects--differing songs by region--and all the orioles I encountered on my
last trip out were singing the Mud Lake dialect.

Another view of that flicker, calling to attract a mate. That's what he was
doing in the other picture too, but it's a little more obvious here.

Speaking of half-decent flicker photos...

I finally got one!

The one feature of note that isn't visible here is the bright yellow
underneath a flicker's wings and tail--although you can see a faint hint of it
at the edge of his folded wing.

Anting
May 21st, 2009
Today, in lieu of pictures, some trivia.
What is anting?
Birds preen their feathers and like to take dust baths or baths in shallow
pools of water--many birds also engage in something called anting, where they
apply insects, usually ants, or other substances to their feathers and bodies.
Strictly, the term anting refers to the use of ants in this activity; however,
for lack of another term, the use of other things in a similar manner is often
also referred to as anting.
Hundreds of different species of birds have been observed treating their
feathers in this unusual way. Songbirds pick up ants and apply them
energetically to feathers; tropical mynas use millipedes similarly; rooks
stand with their wings spread over rising smoke, crows lie down on ant hills,
and poisonous birds may acquire a toxic coating on feathers by rubbing them
with poisonous beetles.
What do birds use for anting?
Birds have been observed using various substances on or in their feathers including:
- Insects and other arthropods, primarily ants, but also beetles, wasps,
millipedes, mealworms, and caterpillars.
- Acid substances such as vinegar, mustard, and citrus juices.
- Plant parts such as onions, citrus peels, berries, apple peels, and
tobacco.
- Manmade substances such as hair tonic, soap suds, and moth balls.
- Smoke--from burning cigarette butts or chimneys.
How do birds ant?
Anting behavior takes at least three forms:
- Active anting: A bird will often pick up one or more ants in its beak and
rub them over its feathers repeatedly. Afterwards, the bird either releases or
eats the ants. Songbirds, such as babblers, jays, tanagers, orioles,
starlings, and weavers use active anting. Other things are used similarly to
anoint the feathers.
- Sometimes birds pick up ants and appear to place them in the feathers,
particularly in the area under the wings, releasing them to wander over the
skin and feathers.
- Passive anting: Some birds spread their wings over an ant hill, fluff up
their feathers and lie down, allowing ants to crawl all over them. Crows,
European jays, and waxbills are among the birds that use "passive anting." In
a similar way, birds may spread their winds over smoke coming out of a chimney
top or over a burning cigarette butt to allow smoke to filter through the
feathers.
Why do birds ant?
No one knows for certain why birds ant--there may be several reasons. Some of
the possibilities are:
- Insect secretions, such as formic acid produced by ants or defensive
chemicals produced by other insects and insect larvae, may kill or repel
external parasites such as lice and mites. Similarly plant essences, smoke,
and chemicals may serve the same purpose.
- Insect secretions may help to condition and maintain feathers, as preen
oil does.
- Birds may place live ants in their feathers to store them as food for
later.
- Crawling insects, or their secretions, may sooth skin irritated by
parasites, molting, or other causes.
- Rubbing an ant over the feathers before eating it may remove formic acid,
making the insect more edible.
- Insects ingested after being rubbed over the feathers may help rid the
bird of internal parasites as well as external parasites.
- Anting, in all its forms, may simply feel good--a lot of birds appear to
enjoy the experience intensely.

New life, and new life in the making

Canada Geese babies have arrived at Mud Lake. I saw these very young goslings
on May 11th, after watching the mother brood for about a month.

Northern Flickers
are a species of ground-foraging woodpeckers. They are in my opinion the most
beautiful woodpeckers in North America, but they are also the most skittish.
I've been trying for over a month to capture their beauty in a picture that
does them justice.
This is not that picture. It is, however, interesting because of what the
flickers appear to be doing...

Warbling Vireo, Night Heron
May 19th, 2009
Even the plain birds deserve their day--especially when they sing as prettily
as a Warbling Vireo!
1680x1050 wallpaper
A much more successful Black-Crowned Night Heron shot than my last one. Still
not a very pretty backdrop, but what can I do for a bird that loves swamps?
This Night Heron seems surprisingly gangly--it's more common for them to look
plump and hunched over. Maybe he lost weight over his long migration.
The strand hanging out at his neck is a breeding plume. Night Herons grow them
quite long in spring to attract mates.

I couldn't get him to come out in the open, but I guess it made a good picture
this way, too.

White-Crowned Sparrow, first of spring
May 15th, 2009
White-Crowned
Sparrows are boreal breeders who appear in Ottawa only in migration--in
fact, their summer range only just edges into northern Ontario. Like most
birds of the far north, they have little fear of humans, hopping out onto open
paths, rocky ledges and exposed branches right in front of us. Needless to
say, this is pleasant for photographers!

And then sometimes mother nature gives you a big, wet kiss

For real. A Baltimore Oriole, my sentimental favorite of all songbirds, landed
in a
flowering tree, posed, preened, and flopped around while I watched
at eye level from a nearby hillside. Mother nature said "mwah!"

Common Grackle. Another one that came out surprisingly painting-like.
