Last weekend I watched two young Red-tailed Hawks flying in circles above a dense suburban neighborhood.
I could tell they were Red-tails by the relative large size, white belly with streaked belly band ( a juvenile trait), the sound of the distinct call and the position of the wings in flight.
I was very proud my skills had grown so much. I watch these birds all time, they are so common in the Philadelphia area. I can tell a Turkey Vulture and a Red-tailed Hawk at a glance, now. I couldn’t before.
I never tire of seeing a Turkey vulture or a Red-tailed Hawk soar for a long time. The birds are usually a speck in the sky before I stopping watching. The gracefulness and elegance of seeing them ride the thermals fascinates me. Thermals are rising columns of sun-heated air that rise from the ground.
Birds of prey are hunters of the sky. They are commonly known as, raptors. Their powerful sharp beaks and claws, seize prey. One of many nice things about these fliers is that they hunt by day and are easily seen.
As a general rule birds of prey are more active in the early morning and early evening. Soaring eagles and hawks need the rising warm air currents (thermals) to soar and will be more active after the sun is up a few hours and the sun has warmed the ground.
Spring and fall are great times to see raptors. At these times many raptors are migrating to more abundant food sources. Many raptors use well-defined flyways to get from place to place. These are hotspots along mountains and coastlines where migrating raptors and other birds converge or fly over. Stationing yourself at one of these locations often means you can see hundreds of migrating birds of many different species in one day.
Although you can see raptors year around, another good time to see raptors is during the nesting season. The nesting season runs from mid-March through June, depending on location. From mid-May through June young birds are fledgling and learning to fly.
When you are outdoors, keep your eyes open. Many people will miss many birds simply because they are not looking for them. A motionless Red-tailed Hawk sitting on the cross arm of a power pole is easy to miss. I often see hawks as I drive along the turnpike in the countryside of Pennsylvania. They perch in roadside trees, searching for prey in the grass and highway median. By looking up you might see a small dark objects in the sky which might be an eagle or hawk soaring above you.
Some things that might actually be a raptor include:
- a fence post that is extra tall
- and extra insulator a power or phone pole
- a rock outcrop with a prominent “point” at the top
- a bird sitting on the wire between poles (possible an American Kestrel)
- in winter, a dark object in a leafless tree
Many people can watch soaring birds for hours on end and marvel at the beauty and elegance of their abilities without ever worrying about exactly what type of raptor they have been admiring. Then there are those who like the challenge of identifying the birds they are seeing. The plumages of raptors differ within a species according to age. Juveniles can look very different from adults. And adults of the same species might have slightly or very different coloration depending on what area they are from.
There are many field guides to Hawks and other birds of prey. I would suggest spending time looking at field guides in your local library or bookstore.
When you are using your field guide remember this important quote from Roger Tory Peterson: “Birds have wings and like to use them”. This means you should watch the bird for as long as possible, taking note of different features before you consult your field guide. If you instantly start looking through your guide when your first see a bird, you may narrow your choices down to three or five birds, and then when you look back through your binoculars to check specific features, the bird is gone.
So, when you are looking at an unknown bird start at the head and work your way to the tail, making note of specific features that you see. Once the bird is gone then consult your field guide.
This week, In Season, will focus on observing birds of prey with several informative posts.
