Death of a Dove

The mourning doves I enjoy so much have been having a rough time since they returned to the yard just a couple of weeks ago. First, the weather changed drastically from hot to cold very quickly, and then, just another day or two later, the Cooper's hawk made a meal of one.

I always do enjoy seeing backyard hawks, despite the fact that when I do it often means my backyard flock has suffered a loss. The most recent casualty was just after the snow began to fall and my sparrows and finches were huddled in their brush pile; the mourning doves, however, do not frequent the shelter that profile provides, and the Cooper's hawk found that weakness. The hawk attacked and landed on the dove, but since the dove is so large and the hawk still young, it wasn't a fatal blow. The hawk was prepared for that, however, and it sunk its talons into the dove to wait. As the dove struggled, the hawk massaged its talons gently, driving them deeper into the dove until the struggle ended.

Staying out in the open for that long as the prey expires, however, is stressful to the hawk. It kept looking around, watching carefully for raiders or other potential predators. As soon as it could - as soon as its meal was less resistant - it flew off to eat in peace in a more secluded, secure place. The evidence of the dove's struggle was left behind in a bright splash of blood on the concrete curbing and a few scattered feathers, all that remained of one of the mourning doves I've been so happy to welcome back to the yard.

While this story has a tragic ending for one dove, I'm also pleased that it wasn't the only dove to have returned recently. While the flock may now be one smaller, I'm still happy to have the company of at least three more mourning doves, feeding and roosting in their patient way. Time will tell if the hawk is even more patient.

60 Degree Freeze

While I haven't been out for much dedicated birding in recent weeks (migration is over and the work schedule is crippling), my husband and I did manage a casual walk at Skipper Bay near Utah Lake a few days ago. As the sun was setting and light draining from the sky, the birding wasn't phenomenal - a northern flicker, small flocks of red-winged blackbirds, a great blue heron on the osprey's now vacant nesting tower. Then in a flash of feathers and a dart through the trees, the action picked up in a lovely wild kingdom moment.

Far more agile than you could believe until you've witnessed it, a sharp-shinned hawk darted through the thick, brushy trees on the west of the path. We saw it perched a few moments later, then flying off toward the south. We thought it had ventured elsewhere in search of a meal until it burst back out of the brush and swooped toward an unwary covey of California quail just on the edge of the path. The quail scattered and the hawk, certainly disgruntled, flew on. We were thrilled to see this just a dozen yards in front of us, but it wasn't until we got to the site of the attack that it was most thrilling.

Still frozen on the side of the trail were two of the quail, both males, sitting utterly still just a scant five feet away. So perfectly were they still that you could scarcely tell they hadn't been victims of the hawk until one blinked. They were crouched low near rocks, and didn't even turn their heads as we approached, then paused to watch them. It wasn't until after I'd taken a few photos and we began to move again that the birds flushed.

Bird camouflage is amazing. Many game birds may seem to have bold plumage when you see them in the open, but when they are still and silent, those same bold markings break up their silhouettes and help them become invisible. A birder can feel even more triumphant for such a sighting, because not only does it bring one a great look at a bird, but often far closer than you can imagine.

Survivor

It can be brutal to be a bird, especially to be a nervous mourning dove in a backyard regularly visited by Cooper's hawks. Such was the case several weeks ago, when I looked out my patio doors and saw what appeared to be the remnants of another hawk hunt - a pile of feathers pressed into the grass. This is a relatively common occurence in my yard, and typically one or two birds fall prey to my hawks every week. Walking closer, however, I realized this time it wasn't simply remnants - the entire bird was still there, as still as death, or so I thought. Coming to within five feet of the bird proved it wasn't death after all, as the bird burst from the battered hollow and flew a few feet away.

Curious about the dove I followed, watching its behavior. It clearly didn't want to fly, but nor did it want to venture far. While it was wary of me it wasn't exhibiting the fear most of my mourning doves do when I step outside, but instead it wandered onto the concrete driveway and it wasn't until the dove paused by the garage door that I realized just how close to death this bird had come. Blood was flowing thickly down its leg, obviously draining from a chest wound where the hawk had begun its interrupted meal. Further examination showed just how many feathers the bird had lost around its neck and chest, giving it a mangled, battered appearance.

I had a choice of what to do; I could have traumatized the bird further by capturing it, keeping it confined until I was able to get it to a rehabilitator several hours later, or I could let it be. Given that it was still capable of flight, was breathing and walking well, and knew that the best thing to do was to keep still and slow, I let it be. I kept checking it throughout the day, and it moved locations, seeking shade and shelter which I was happy to give it. When it roosted under the lilac in the evening, I left a dish of water a few inches away and sprinkled some seed nearby for a meal.

Never having known a hawk to pull down its prey but abandon the meal when the bird was so gravely injured, I reexamined the scene of the attack. Sure enough, lightly tossed on the grass I found a clue - one tawny feather obviously from the chest of the hawk itself. This dove had fought back, forcing the hawk to abandon its meal if for nothing more than aggravation - dinner shouldn't bite.

Sad to say, the dove did not survive the night; I found it the next morning still beneath the lilac bush, though it had obviously fed and drank as best it could during the night. One might question, then, why I consider this mourning dove a survivor when it did not, in fact, survive. It may have died, but it was never prey. It might not have lived, but it didn't die under a hawk's talons. If that's not surviving when you're a bird in a world filled with predators, what is?

Hunting Hawk

I'm always thrilled when my backyard birds put on a wild kingdom act, whether it's feeder aggression threat displays, begging fledglings, bathing, preening, or stretching out in the sun. The most exciting events, however, are hunting hawks, and I've been priviledged recently to have my Cooper's hawk, Dart, attack in my yard.

Many birders have a soft spot for their backyard birds and despair if a hawk scatters the flock or manages to catch a songbird. I look at the hunt a bit differently: these birds don't hunt for fun or sport, and only about one tenth of the time are they successful in catching their dinner. They don't waste food, and they're just as vital a part of ecological health as any bird. The birds a hawk catches are often sick, weak, or simply have slower reflexes than their peers, and thus a flock is strengthened whenever one of these weaker links falls prey to a hawk.

This hunt seemed to be one of Dart's most successful. While Cooper's hawks regularly feed on birds, including larger birds such as doves, her juvenile reflexes and strength aren't as sharpened as an adult's would be. After catching this unfortunate Eurasian collared dove (you can tell by the size and coloration of the bird), she fluttered with it for several feet in ungainly hops before finally getting good enough purchase with her talons to carry it over the fence and to a more secluded spot to dine. I particularly like the photo I managed to snap of her regarding the dove, as if wondering just what to do next.

Hawks are outstanding creatures, and both sharp-shinned and Cooper's hawks are regular visitors to backyards here in Utah. For more information, I highly recommend...

Most of all, remember to enjoy the hawks when they grace your yard with a visit. It may not be the ideal image you have of backyard birdfeeding, but any visit from a less frequent bird is a sighting to be enjoyed and treasured. Happy birding!

Wilder Kingdom

The past few days have been exciting ones. While absently watching the American goldfinches feeding as I walked across the room, I was startled when one of them flew up and swiped the window. At first I thought the bird was merely agitated -- the pine siskins have been getting more and more aggressively lately -- but as it swirled away I realized it was panicked, and with good reason. A flash of red tail and razor sharp wings burst past the feeder, and I thought Spook had again come to visit. Still, while he's no longer strictly a juvenile sharp shinned hawk, he's not quite as adept as he'd undoubtedly wish to be, and the attack was unsuccessful. I went about my business and the birds went about theirs, eventually returning for their late afternoon feed.

At dinner that evening less than an hour later -- my place at the table faces the patio door -- I smiled indulgently while a house finch fluttered toward the one small tree we have. Within seconds, however, my indulgent smile became an open-mouthed gasp as that red tailed fiend again dove, apparently from the roof of the house, perhaps from the aerial antenna we've never bothered to remove. The attack was vicious, with a very determined bird of prey and a hapless finch who managed, how I haven't a clue, to escape despite being terrorized within the branches of larger neighboring trees before his pursuer flew to a nearby electrical pole. The pace of the attack, the agility of the attacker, and the burst of red, white, and grayish blue plumage immediately had me suspicious -- this wasn't Spook. Only a brief observation through my field binoculars was necessary to see the prominent eye streaks, heavy spots, and bold coloration of a new backyard guest and a new addition to my life list -- an American kestrel.

It's fascinating to see the differences between the two birds' attacks. The kestrel is much more aggressive and less patient, waiting for just a few moments on one perch before seeking a better vantage point. Spook, on the other hand, will wait for long periods to observe his territory before making a move. Perhaps, as a slightly larger bird, he knows his agility -- while always exceptional -- is just a fraction slower than a kestrel's, and his behavior needs to be a bit different if he will be successful finding dinner.

Spook has returned to the yard for the past two days, resting both in the adjacent tree and coming all the way into our yard on the small tree where the kestrel staged that blatant attack. He looks disgruntled -- this is, after all, his territory -- and perhaps he'll be around a bit more frequently now to ensure that any meals found within its borders are his own. Whomever manages to dine here will be welcome, of course, whether they prefer seeds or larger fare. Will Kess return? I can't say, but if Spook finds out, our backyard wild kingdom is sure to get even wilder still.

A Hawk's Life

Over the weekend we were struck by yet another winter storm, this one with wet, heavy snow in varying intensities throughout the day. Yet even a heavy snow does not dampen bird activity, and in the midafternoon we discovered that our yard was under strict surveillance: Spook had returned.

It is fascinating to really watch a sharp shinned hawk, or any bird of prey. For long periods of time he perched attentively where he had good visibility -- at the top of a power pole, on the peak of a nearby garage, or in a tree along the property line. Once, for a moment, he alighted on our fence, but only for as long as it took to regain his balance before finding a more comfortable perch. The smaller birds: the finches, sparrows, and siskins, were conspicuous by their absence, but eventually the American goldfinches began to taunt our accipiter friend. One finch, or several, would fly erratically near the hawk, just out of reach of a quick strike but clearly meant to be seen. Spook might shift his weight, eyeing this seemingly easy prey, but he did not easily take the bait. Only when the finches would venture just a tad too close would he launch and dive after them, testing both his and their agility to the limit.

After less than a minute of frenetic activity, Spook would find another perch and rest there, his head continually scanning the landscape in a methodical pattern, searching for a morsel. After a time, the finch taunting would begin again only to culminate in another intense chase of aerobatics.

In the hour or more that he lurked around our yard, Spook's appetite must only have grown because his attacks were unsuccessful. Yet this juvenile hawk (clearly marked by the white feathers still showing through his darker plumage) is succeeding at survival, because even in the coldest, most unforgiving winter weather, he continues to hunt, to live, and ultimately, to soar. In the midst of the darkest winter days, if we can remember his perseverance, we too shall grow stronger and wiser as we survive until spring.

Exploding Trees

While checking the seed in the feeders this afternoon (I'm about to travel for the holiday -- hopefully to see new birds!), I was walking along the side of the garage when our neighbor's apple tree exploded. Or at least, one branch exploded in a noisy burst of leaves and action.

Sharp shinned hawks are small birds of prey, and don't make very big explosions.

Our juvenile hawk was lurking in the tree, waiting for his moment to dine. He was literally on the tail of either a house finch or house sparrow -- at the speeds they were flying it was impossible to tell -- and they veered between the houses, reappearing a second or two later in the opposite direction. Across our yard and just barely above trees across the property line they flew, the smaller bird darting and obviously terrified, but the hawk keeping up with precise determination. He dove, but missed, and the smaller bird flew rapidly away frantically chirping a warning while the hawk caught a small updraft and glided more leisurely in the opposite direction, ostensibly to find his next meal elsewhere.

In these few seconds of wild kingdom action, it was fascinating to observe the hawk's beautiful and acrobatic flight. Though he was unsuccessful in this attempt, his skills are obviously advancing from what they were earlier in the season. Our dear Spook is growing up.

Just one week left to vote in November's poll: How many species are on your life list?
