"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.

Red-shouldered Hawk

"Red Rover, Red Rover,"
"Send Robin On Over!"

     I hated that game. Played on hot summer nights with neighborhood kids, I always felt like I was on the wrong side. Helpless, tossed, given up; I felt like a loser. I don't remember what the rules were, something about being called out of a group to physically break through a line of opposing kids. I distinctly recall the red-faced panicky feeling. I could never break through the line which was why I was always called. My head swam and my heart raced as I was flung from one side to the other, kids shouting, me nearly falling down when whipped across the line. I was not an athletic child. I was scrawny with tangled hair and huge, chipped beaverish front teeth. I didn't get breasts or my first period until I was  nearly forty. I was a geek before there were geeks!
     I liked science and could name the organisms floating in pond water under the microscope, a gift from my father. Knowing things was how I got a charge and often times, was how I was used by other kids. I was rarely invited to birthday parties or sleep overs but regularly asked to give the answers to tests or homework assignments. Knowing the answers to things was the one thing I could do that gave me an edge. But these days, when I see something like this hawk, I feel like a winner. Seeing it was exhilarating! I was driving home from the post office when out of the corner of my eye, I saw this beast on the utility line. I conducted a U turn on Route 209, camera on the passenger's seat, at the ready, and wound down the window. I knew right away that this was not a hawk I was familiar with.
    At first, when I looked at the photos, I couldn't believe that what it looked like could possibly be true. My palms started to sweat. I recognized right away what it was, but then did not trust my gut. I'm not the most experienced birder, plus I lack confidence in what I do know. I second guess myself. When it comes to hawks especially, I've fallen and I can't get up! In the world of birding it's important to pay attention to details and not jump the gun on identification; credibility is at stake. After all, when making bird identifications there's rarely DNA available. It's what the birder sees that counts. In my case, I'm a photographer as well, which gives me an edge, but not proof positive. When and where the photo was taken is as important as the subject itself.
    I poured through The Sibley Guide To Birds, The Audubon Society Field Guide To North American Birds, Roger Tory Peterson's Field Guide To Birds East Of The Rockies, then consulted the web sites Whatbird and Allaboutbirds. My head was spinning! "Red Rover, Red Rover........." I could hear them screaming and feel myself falling as I churned the pages. Still not confident, I sent the photos to CHIT, my top secret, crack, hawk identification team. When I e mailed the photos, I held my breath and committed that  I thought it was a juvenile, Red-shouldered hawk, highly unusual in Maine in winter. I gulped, pulling the neck of my shirt away from my throat. "Oh God, I'm going to look like a total idiot," I feared. I thought I was going to pass out! Give me a mean spirited kids game over birding any day! At least kids grow out of it.
