Bird of the Week XXXlll - Tuesday, May 31st, 2011




This weeks "Bird of the Week" is the Chimney swift. A "flying cigar," the Chimney Swift is rarely seen perched. Its high-pitched twittering is a familiar sound during summertime as it flies high above, catching small flying insects. The Chimney swift has a fast, erratic flight. They are among the most aerial of birds, flying almost constantly except when at the nest or roosting at night. The Chimney Swift bathes in flight, gliding down to water, smacking the surface with its breast, then bouncing up and shaking the water from its plumage as it flies away. Chimney swifts feed on flying insects by pursuing the flying insects and catches them in their bill. They feeds in flocks or alone. Chimney swifts can devour over 1,000 insects in a day!

It's nest is a half saucer of woven small twigs held together with saliva. It's glued with saliva to inside wall of chimney.

This week's "Bird of the Week" is the Northern flicker. This large woodpecker is the fourth woodpecker to be on the Bird of the Week, along with the Downy, Hairy, and Red-bellied woodpeckers. Flickers are large, distinctive woodpeckers that are often seen on the ground in open areas, eating ants and beetles. In flight, these large brown, woodpeckers have a white rump that is very visible and a flash of yellow in the wing. The face is gray and there is a black patch just below the throat. The male has a red "moustache". There call is a long, loud, "laughing-like" sound. Look for flickers in open habitats near trees, including woodlands, edges, yards, and parks.

Bird of the Week - XXlX - Monday, April 25th, 2011



This was taken in a backyard on Springvale Rd. in Reading
 This week's "Bird of the Week" is the Eastern Screech owl. This small owl, about 10", has ear tufts and can be found in either a brownish-gray color or a reddish-brown color. The male and female birds look alike, with the female slightly larger. Believe it or not, the Screech owl is common in Reading, however, because it is nocturnal, we don't often see or hear it. They found in most habitats with trees, including urban and suburban areas. If you are careful, patient, and lucky enough, you may spot a Screech owl sitting in a hole in a tree. You may hear one of it's two common calls at night; a descending whistled whinny, or a whistled trill on one pitch.




The Screech owl hunts and eats large insects, small rodents, crayfish, earthworms, and small songbirds. They nest in tree cavities (holes) and will readily nest in man-made nest boxes.
