"What Hawk Are You?" Red-Shouldered & Red-Tailed Hawks

Red-shouldered hawk photographed on January 26, 2011, Phippsburg, Maine

Red-shouldered hawks are often confused with the Red-tailed Hawk, another species of hawk seen in the photos below.



"Are you looking at my red tail? Flashy, isn't it?"
     Red-tailed hawk photographed in Maine in 2009

     The top two photographs were taken through my living room windows yesterday. When the bird landed in the tree, I was still in my bathrobe sitting in front of my computer. I had been sitting there for hours deep in concentration. Nonetheless, in my peripheral vision I sensed, more than saw, the movement across the sky. I leaped up, grabbed the camera and slammed off some shots before it disappeared. My brain immediately said "Red-tailed hawk," but I quickly realized it was not. My brain also said "Ouch! My back!"
     It took study to identify this as a Red-shouldered hawk. I have seen and written about Red-shouldered hawks before, but it seemed an unlikely bird in the winter. The Northeastern populations migrate to Mexico. The last Red-shouldered hawk recorded in this county was in October of 2010. This raptor eats rodents: moles, voles and mice and some snakes, creatures which are hiding under the snow now. But, there are plenty of Red squirrels in our spruce woods (and my bird feeders) and the Red-shouldered will also hunt other birds. It's avian brethren aren't its favorites though, nor is it built for bird tagging speed. This hawk sits on perches as seen here then swoops to the ground to grab its prey. Sometimes they snatch birds and large insects from mid air. They also hunt on the ground for burrowing critters and will hop along after a target, an unusual behavior for hawks.
     So why was this hawk still here since most of its favored foods have disappeared? We don't know. So, I'm going to guess that it's a bad procrastinator with a major case of denial. It just waited too long dilly dallying around on the Maine coast. I have great empathy for
this; I was able to see the bird because I have the same   
problems. I photographed it after noon and I was still in my bathrobe. Yet again, I too had failed to migrate to the next venue. My laundry still wasn't done; my kitchen was a mess and bills still needed to be paid.
     I'm ashamed to admit this, but two of my favorite TV shows these days are The Biggest Loser and Hoarders. I've been trudging along on a weight loss journey for the past year and along the way, I've found The Biggest Loser inspirational. There's a lot of whiny drama, theirs and mine, but some useful tips, too.
     The people in Biggest Loser and Hoarders share in common that their lives are completely out of control. The contestants have stuffed their faces and bloated their bodies to a medical diagnosis of super, morbid obesity. The Hoarders are stuffocating on the stuff  around them until their homes have become uninhabitable junk heaps. Denial and procrastination got them all there one newspaper pile and one Twinkies at a time.
     Viewers of these shows probably fall into two categories: those who feel differentiated and thus, safer in contrast to what they see, and those who feel communality with what they see. I fall into the latter category. I watch those shows and think "Oh God, that could so easily be me!" It gets me on the treadmill and loading the dishwasher. So far, I've yet to be mistaken for a member of the cast of either show, but my day could come.
     Amongst  the cast of Maine hawks, juvenile Red-shouldered hawks are most likely to be confused with juvenile Broad-winged hawks. They can be distinguished by their longer tail and crescent-like wing markings. If you look at the above flight shot and squint, the crescents on the wings will stand out. You also can see how long the wings are. Red-shouldered hawks flap their wings a little differently, too. They are members of the genus Buteo, a group of medium sized raptors with broad wings and robust bodies. Because they kill mammals on the ground rather than chase other birds around the skies like Accipiter hawks, they are built for power not speed. So, their wings are broader and longer than their Accipiter cousins (see Cooper's & Sharp-shinned). Birds constructed for speed have longer tails for quicker in- flight maneuvering, too. Red-shouldered hawks are also easily confused with Red-tailed hawks, another big, Buteo which we more often see here in the winter.
 The Red-shouldered is one of our most vocal hawks bested only by ospreys. Crows often mob them, but legend has it that they also gang up with crows against Great Horned owls that prey on nestlings. When you hear crows screeching in the trees, look for hawks. A sign of an active Red-shouldered hawk nest is poop on the ground. By the time their nestlings are five days old, they can shoot poop over the edge of the nest. These hawks don't need inspirational television programming for good housekeeping, but it might nudge them toward timely migration.

Broad-winged - Hopefully

Broad-winged Hawk in Phippsburg. Broad-wings are a type of buteo. They are birds of prey and hunt small animals from a perch like this. Shy birds, they usually prefer the woods. They are migratory and spend the winters in tropical forests of South America. They migrate in huge flocks or 'kettles' of hundreds to thousands of birds. At about 15" they are a stocky little hawk.

I'm going to go with Broad-winged Hawk on this identification. After my last hawk fiasco, I'm hopeful that I'm correct this time. I'm going with Broad-winged because of the the thick barring of the breast and the relatively short tail. It also hollered several times, "Look, you! Get it right this time; I'm a Broad-winged. Got that?" I could hear it plainly from my open car window. I had been whizzing my way homeward from a long day of Weeding For Dollars when I spied it sitting on a power line on Rt. 209 in Phippsburg. For those of you who know the area, the hawk was sitting just south of the elelmentary school. I saw the  bird on the wire, but it was actually too close for my long lens. I continued then doubled back around so that when I came back I was across the road. I never got out of the car. While I sat there shooting, lots of people drove by. Many of them slowed down to see what I was looking at, including one of my neighbors. They thought my lens, or "that thing," was protruding too far out of the window into the traffic lane and called to tell me so. I always look to see where my car is in situations like that. I do not want to cause any accidents or even inconveniences for other people. My car was four feet from the painted line on the side of the road, well out of the way. The school bus stopped not too far from me to let out some kids. I thought it would be nice if the bus driver had said to the kids "Look! There's a hawk on the power line and that's a National Geographic photographer right here in your home town!" I would like to think of myself as inspirational to those children even if I'm not a Nat. Geo. photographer. Maybe one day, one of them will be a famous photographer and perhaps I will have helped them on their way one fine day when they were coming home from school.
