If Chimney Swifts have moved into your chimney, there is no reason to worry. They will not cause any damage and will stay only temporarily. There are a variety of ways that you can support Chimney Swift conservation.
If you have a chimney, leave it uncapped and have it cleaned in March after the winter use but before Chimney Swifts arrive in our area. In order to help ensure that swifts have plenty of food, consider reducing or eliminating pesticide use.

There are a number of ways to tell them apart. First, listen to the Chimney Swift call which is very distinctive and can be heard from a great distance. The sounds that bats make are undetectable by humans in the outdoors; there is a small chance that you will hear bat sounds when they are in an enclosed area.
Another way to tell the difference is that Chimney Swifts fly at a much higher elevation than bats do. Bats become active in the evening whereas Chimney Swifts enter the roost at dusk to settle in for the night. Listen to their calls by clicking here. Contact Sarah, skoenig aswp. Chimney Swifts.

What other type of birds are Chimney Swifts related to? Are Chimney Swifts Threatened? Chimney Swifts are easily recognized. The plumage of the male and female are similar as is that of the juvenile birds.
They have a dark gray brown upper body which is paler on the throat, chest, and under wings. The only distinguishable features of the sub-adults are their slightly shorter wings.
They are constantly in flight alternating between very rapid wing beats, then a gliding motion with rigid wings held out. While in flight they make a continual chattering and twittering vocalizations.
Very few people ever have the opportunity to see them at rest since Chimney Swifts are incapable of perching on a branch or ledge as other birds. In fact these swifts are so specialized and adapted to clinging to vertical surfaces that they cannot perch or even stand on their extremely short legs. Their tiny feet have four hook shaped toes they use to hold on to rough vertical surfaces. These adaptations have allowed swifts, who traditionally used hollow trees, to use chimneys.
Chimney Swifts actively nest from May through July. But with the loss of many giant hollow trees that were cleared for agriculture and development over the previous two centuries, these birds became quite comfortable in urbanized areas where numerous open chimneys built with stone and mortared brick were almost exact replicas of the original trees used for nesting. Their nest is made of twigs glued together and onto the wall of the chimney with their saliva.
The cup shaped nests are located deep enough down the chimney to provide shade from the hot sun and protection against summer rains. The female will lay three to seven white eggs, which she will cover at night. Once the clutch is complete incubation begins. The eggs will hatch in days but it will take another 30 days before the young are ready to leave the nest.
Chimney swifts can nest more than once in a season if a nest is destroyed. During the nesting phase of Chimney Swifts there will almost always be a single breeding pair to a chimney. The brooding and raising of young is between June and August. They are loudest when being fed by their parents.
However, by the time they are loud enough for you to hear them, they are almost old enough to feed themselves. You know it, that screeching sound a belt of some form of machinery makes in its death throes. Every single time someone walked past them, the riotous sound would shoot forth, and everyone would laugh at the ridiculousness. But things got really absurd when they went into the shed. Both aviaries being full, they ended up hanging from a large net hung in the squirrel shed emptied of squirrels.
On a regular baby bird feeding shift, Jennifer decided to have someone show me how to feed these characters. Not too different from other birds, but a few things to note. One, watch where you put your feet. Two, mealworms have to be soaked in water because this is how the young are hydrated. How hard can that be? So, I headed into the shed on my own, wet worms in tow, full of confidence.
But this turned out to be the height of absurdity to accomplish. Young swifts do not stay put. Feed one and everyone flies into a pile so as to soon make it very hard to figure out who has been fed and who has not. Everyone was rowdily screaming, and within a couple of minutes, I found myself wearing a fair number of them literally hanging on my clothes and in my hair. Soon the entire place had erupted into screaming shrieks and a flutter of practicing wings, knocking each other out of the way to get as many worms as they can.
