Some early morning in May, when the trees are filled with migrants, take a stroll thru the woods! The world is filled with bird notes and you listen to the symphony of sound. Then you hear a questioning whisper “pee-a-wee,” as if some stranger wondered if he should or could make himself heard. Finally you locate the bird with the plaintive note and find a little flycatcher, but since he is sitting on a well-shaded limb, you have trouble with the markings. Eventually you see that he is about sparrow-size, is a dusky olive-brown above with whitish under parts, lacks an eye ring but shows 2 distinct wing bars. That is the Eastern Wood Pewee.
Western observers will find the Western Wood Pewee to be a bird with nearly the same markings and habits. However, the western bird has a more nasal, single note song. Tho both birds place their nests on tops of limbs, the Eastern Wood Pewee builds a shallower structure, well covered with lichens and cobwebs, giving it the appearance of a knot on the limb. Both nest in rather open situations. Both birds feed heavily on insects and spiders, including many harmful weevils, flies and beetles. Unfortunately they draw no distinction between useful parasites and pests.
On summer breeze
We hear your call,
You speak your name
But with a drawl.
Tree Swallow
Iridoprocne bicolor
The frost hardly has left the ground, or the peepers and cricket frogs assembled their chorus, when flocks of these swallows can be seen winging their way northward. First flights include only the rugged males which arrive well in advance of their mates. They also are one of the last species of swallows to migrate in the fall. These birds show whitish under parts, while the upper parts are a greenish steel-blue. Western observers might confuse this bird with the Violet-green Swallow but remember that the latter shows a conspicuous white patch on each side of the rump.
Tree Swallows prefer a location near water and soon will occupy holes in stumps so located: however, bird houses are acceptable. They do not choose to nest in colonies and will defend their nesting site with vigor. Those who erect nesting boxes for these swallows might find it necessary to help them evict House Sparrows which often take a liking to their homes. Flying insects form the major portion of this bird’s food. These include numerous mosquitoes and other insects which hatch on or near water, for that seems to be their favorite feeding ground. Other foods include bayberry and wax myrtle berries, which are sought during migration.
