|Shiann on point with Chimney Swifts|
"The very loudest sounds are made by the babies when they are being fed by the parents. Although it is quite loud, there will be only one active nest in any chimney at one time. Normally by the time the babies become loud enough to hear, they are less than a couple of weeks from being old enough to feed themselves. After that, most of the loud noise will be over." Chimneyswifts.orgChimney Swifts (Chaetura pelagica) are frequently described as flying cigars. They appear to streak through the sky with their wings beats alternately, something that took years and advanced photography to disprove to the prevailing opinion of ornithologists.

They build nests in hollow trees and chimneys using twigs with their saliva as glue. Even more impressive, they collect their twigs on the fly, grabbing them with their beak or claws. If the twig doesn't break off, the bird tumbles in the air, then frequently makes a second pass.
Swifts are gregarious and migrate to South America in large flocks. We now look forward to the first twitter of spring in the house. Shiann still hasn't got it figured out.
Cornell has sound files of their chatter.
