CSI: Pigeon Town

Not the bird from last week, a young Cooper's Hawk from a nearby park last winter.

About mid-morning last Friday, while I was working at my desk in the back of the house, I heard a crow in the front yard screeching his displeasure at something.  It went on for several minutes, and I thought about going out to see what was bothering him -- following the lead of agitated crows usually leads to something interesting -- but this was only one crow, not a mob, and I was focused on the blog post I was writing, so I didn't get up.  A few minutes later my roommate Dan called me, from the front yard.  He had just gotten home, and he was whispering into his cell phone, "Dude, get the camera.  There's a small hawk in the tree outside.  Hurry."

I got the camera (which is not stored conveniently on the table by the door any more, since my dog Zeke decided to chew up one of my lenses) but by the time I got to the window, the hawk had noticed Dan and taken off.  I didn't get to see him.  However, Dan paged through the field guide and quickly identified him as a Cooper's Hawk.  That made sense, because I know there are Cooper's Hawks in this area.  I've seen them more than once in the park where I take Zeke to play.  I was mildly disappointed that I didn't get to see him myself, since I've never actually seen a hawk in our yard.

A few hours later, we were getting ready to go shopping, and Dan took the dogs out before we left.  I followed him a few minutes later and he told me, "Don't look over the side rail.  There's been a death."

My first thought was that it must be one of the rats that live under the fence.  I haven't seen them in a while, and I've been a little worried about what happened to them.  But unfortunately, this was a death that hit even closer to home.

It was one of the pigeons.

Anyone who reads my blog probably knows that I am fond of pigeons.  I take care of the little collection of "misfit" pigeons who hang out in this neighborhood -- mostly because they are centered around Timmy.  I have a history with Timmy, and feel some responsibility for him.  And I enjoy watching the pigeons when they come to eat (and often squabble) on my front deck.  They don't hang around here otherwise -- even Timmy has stopped hanging around much other than mealtimes -- so they aren't a nuisance to me or the neighbors.  I often see them perched on the power lines behind the house, watching.  When I put food down they begin to swoop in.

The "victim", fortunately, was not Timmy or Timmy's Friend.

The dead pigeon was not Timmy, or "Timmy's Friend".  (You can see my earlier posts about Timmy and the other pigeons here and here.)  In fact, judging by the wing patterns, it wasn't a pigeon I was familiar with.  I examined the body and the "crime scene" -- and I took lots of photos, which I'm going to spare my readers, since they are pretty gruesome.  Suffice it to say that the pigeon was apparently eating on the rail when it was attacked.  It looks like it was killed almost instantly, because it was on the ground just below the rail.  Its head was gone, and its crop was still filled with undigested seed which it had obviously just eaten.  There were blood and feathers around the body, and more at another spot a few feet away, under the stairs.

My first thought was that a cat was the culprit.  There are occasionally free roaming cats in our neighborhood, and any bird lover has to be concerned.  I put off bird feeding for many years because the area I used to live in -- Ballard -- was full of feral and semi-feral cats.  Don't get me wrong, I'm not anti-cat.  But I am anti-outdoor cats.  At the wildlife center where I volunteer, a very large percentage of all the animal injuries that come in -- especially birds -- are cat attacks.  Outdoor cats are an environmental horror story.  But I'll come back to that in a later post.

It didn't even occur to me, at first, that the Hawk killed the pigeon.  But of course, that was the most likely scenario.  So I sent my crime scene photos off to my friend Kevin, who's the staff naturalist at Paws WildlifeCenter.  Here's what he said:

"From looking at the photos of the pigeon, I would say you are looking at the work of a hawk, rather than the work of a cat.  First of all, it looks like the pigeon’s tail and rump feathers are intact.  In almost all cat attacks you will see wounds over the rump and missing tail feathers because the cat attacks from behind as the bird tries to fly away.  Hawks usually hit much farther forward on the body.  Once they have a good grip on their prey, they kill it by biting through one of the cervical vertebrae at the back of the neck.  They then tend to eat from the head down.  Hawks pluck the feathers from the area in which they wish to feed.  This leaves a scattered pile of loose but completely intact feathers.  Cats bite into birds right through the feathers. Feathers are generally pulled away in clumps, usually with skin still attached, and the feathers themselves are often broken or otherwise damaged.  The loose feathers around this pigeon’s body all look like they have been individually plucked, again indicating a hawk rather than a cat."

Sad news.  But on the other hand, I had a Cooper's Hawk lunching in my yard.

Pigeon Watch

I was talking about pigeons. (Here)

The common pigeon -- the Rock Dove or Rock Pigeon familiar to city dwellers around the world -- is one of those ubiquitous creatures -- like crows -- that we see so often that we almost don't see them at all.  Not as flashy or charismatic as crows, they have been with us for a very long time.  Though most of us don't see them this way, pigeons belong to a select group of animals -- along with dogs, horses and possibly cats -- that have been companions of humans and contributors to our civilization for thousands and thousands of years. 

Ballard (Seattle, WA) June, 2009

Just consider this:  all the Rock Pigeons around the world are the descendants of domesticated birds. We know that, between five and ten thousand years ago, Egyptians were using pigeons to carry messages up and down the Nile. We also know that there were already feral pigeons living in the streets of ancient Rome, pretty much the way they do now. They were introduced into North America probably in the 1600's from Europe, and the Army was still using them to send messages as late as World Wars I and II.   Properly speaking, they are not wild birds; they are feral -- domesticated animals that have returned to the wild.  Sort of.  You don't find many Rock Pigeons out in the forest (where their wild cousins do still live -- in this area, we have Band-Tailed Pigeons and Mourning Doves for instance).  They are urban animals.  Or, if you prefer (I do), civilized.

Many of these stories, and much more, are related in Pigeons: The Fascinating Saga of the World's More Revered and Reviled Bird by Andrew D. Blechman.  I first read this book a couple of years ago, and have gone back to it many times to check on certain anecdotes or re-read certain stories.  It is a rich, fascinating popular science book that not only gives us the history of the bird, but also introduces us to the incredible cast of characters and subcultures that have grown up around pigeons in the present day.  From weird pigeon hunts to racers to oddball environmentalists to good old fashioned breeders.  The pigeon has inspired more hate and love than just about any other bird (People as diverse as Charles Darwin, who bred pigeons while developing his theory of natural selection, and Mike Tyson, who has been a lifelong lover of pigeons, raised them as a child, and reputedly had his first fight with an older boy who killed one of his birds.)

TheCornell Lab of Ornithology has a special "Urban Bird Project" and as part of that project they have "Operation Pigeon Watch".  Now, next to watching dogs play, and seagulls fly, and the endlessly inventive antics of crows, there are few things I find more entertaining than pigeons. (Okay, Jennifer Aniston, but that's a whole different topic.)  So when I found out about project Pigeon Watch, I was hooked.  As I've mentioned before, I have a resident pigeon at my house who I call Timmy.  I call him a special needs pigeon because he seems to be a little ... well, handicapped.  But he's a big, beautiful healthy looking pigeon none-the-less.   Lately, Timmy has been showing up with a friend.  I think of "her" as Timmy's girlfriend, but of course I have no idea of either of their genders.  She's smaller than Timmy, with darker colored wings. 

Timmy!

There are something like 28 "morphs" -- or different color patterns -- recognized for the feral Rock Pigeon, but Cornell's Pigeon Watch has narrowed it down to five.  Timmy, for instance, is a "checker" because of the checker like pattern on his wings.  Checker's can vary from light gray with a little black, like Timmy, to much darker patterns.  I believe that Timmy's friend (who is shier and harder to photograph) might also be a checker, but with much darker wing patterns than Timmy's.

Timmy's "parents", West Seattle, summer 2010

One of the goals of the pigeon watch program is to observe mating habits among pigeons and learn which morphs mate with which others (to determine if they show a preference).  I had a chance to observe Timmy's parents, when I first moved here -- the birds I assume were Timmy's parents because they were all sharing a nest -- and I believe I witnessed courting behavior several times.  Pigeons court throughout the year, although (according to Cornell and other sources) they are more likely to mate in late winter or early spring.  Once they mate though, they mate for life.  I don't have the opportunity to observe the rest of the family any more, as they are all gone.  But I will be watching Timmy and his friend whenever I get the chance.

Birds of Winter

Winter was  unusually wet and dismal in Seattle this year.  I grew up in Florida where the length of the days doesn't change significantly through the year, and maybe for that reason I'm generally not bothered by seasonal depression.  But this year I felt the winter blues.   This is the kind of weather people who don't live here think we have all the time.  And it hasn't let up for spring -- our March was the wettest on record, and April continues to be sodden.  But through all this gloom (and a fair bit of personal stress) one bright spot of pleasure and distraction has remained:  my bird feeders.

Last year I relocated from Ballard, just north of downtown Seattle, where I lived in one of the more industrial neighborhoods in town, to West Seattle.  We are now about as far South as you can go and still be in the city.  The neighborhood has more of a suburban feel, lots of trees along the streets, and we are surrounded by parks and greenbelts.  The difference in the bird life is amazing.  

 In Ballard, my neighborhood was dominated almost entirely by crows, who shared their turf uneasily with seagulls, pigeons, starlings, and sparrows.

   

(The sparrows lived mostly in the parking garage of the Safeway across the street and nested in the small trees along the sidewalk.  What is it with sparrows and grocery stores?  It is an almost ubiquitous combination in Seattle.)  And our neighborhood was so thick with feral cats that I didn't dare set up bird feeders.

Here in West Seattle, the situation is very different.  Bird activity is much higher, and the number of species are far greater.  Even though I moved here at the end of summer and didn't get my feeders set up until early Autumn, I've had amazing success.  I have positively identified 17 different species in my yard over the winter. (Not counting others -- including a Red-Tailed Hawk -- that have been in the neighborhood, but never actually on my property.)  This is my "yard list" for the winter and early Spring: 

Seen on our property (West Seattle)  June 2010 through December 31, 2010

1.       American Goldfinch (winter plumage)

2.       American Robin

3.       Anna's hummingbird

4.       Bewick's Wren

5.       Black Capped Chickadee

6.       Crow

7.       Dark-eyed Juncos

8.       European Starlings

9.       Northern Flicker

10.   Red-breasted Nuthatch

11.   Rock Pigeons

12.   Steller's Jay

Jan 1st 2011 through April 14 2011

13.   House Finch

14.   Song Sparrow

15.   Yellow-rumped warbler

16.   Bushtit

17.   House Sparrow

I'm pretty happy with that list.

 

Some of the birds have come to seem like constant companions -- friends even.   The chickadees, for instance, have been here almost every day.  Their curiosity and fearlessness makes them great birds for close observation.   

 

Also, the Dark-eyed Juncos, who not only eat at my feeders and in the yard below, but frequently even on the railing of my deck.  One Junco in particular, a fellow with prominent leucism (lack of pigment)  on his face, was a frequent guest throughout the winter.

 Anna's Hummingbirds have been another real blessing this winter.  They've hung out in my yard through snow, rain, heavy winds and (occasionally) sun.  There is at least one male/female pair in the neighborhood, so I am hoping to see hummingbird fledglings before too long. (Here you see a noticeably sluggish Anna's Hummingbird at my feeder during our first big snow in November. I had to go out every hour or so and bring the feeder in to thaw it out.)

This really just scratches the surface of the pleasure my bird watching has given me over the past eight months or so.  As I go forward with this blog, I plan to give many of my avian friends a more in depth look, and also to keep you up to date on the excitement of Spring in West Seattle.

Let me leave you, though, with a shot of one of my non-bird "friends" -- the clever and resourceful nemesis of birdfeeders everywhere.  I have more to say about him in the future as well.
