Chimney Swift  (Chaetura pelagica)

Chimney Swifts are Federally Protected Birds!

Chimney Swift

The  Chimney Swift  is one of four regularly occurring species of swifts found in North America and the most common swift found east of the Rockies. They got their name because they have become accustomed to building their nests in chimneys as well as abandoned buildings and occasionally stone wells.

Adult chimney swifts are most commonly seen in flight; usually in groups. When soaring, their long, scythe-shaped wings span about 12 1/2 inches, supporting a proportionately short body with a squared-off tail. You will notice a flickering, bat-like flight when flapping that is due to short and massive wing bones. Watching swifts is truly a magnificent as they create spectacular aerial ballets. These acrobatic moves are most often created as they patrol the skies for mosquitoes and the other small flying insects that constitute the majority of their diet. You will hear a sharp chipping or ticking call that accompanies the swifts’ as they fly.

At rest, an average 5-inch, 8-ounce adult is sooty gray to black with the throat slightly lighter or even silvery gray, in color. The sexes are identical in appearance. Both the claws and tail bristles are used to cling to rough vertical surfaces. This is one reason they like to nest in chimneys. Swifts are actually unable to perch or stand upright in pas serine fashion.

Where do Chimney Swifts Come From?

Chimney Swifts winter in the Amazon Basin of Peru. They arrive in the continental United States in late March and are gone by early November. Nesting begins in May and can continue into August. Chimney swifts are usually single-brooded, which means they lay eggs once a season. The female normally lays three to five white eggs in a nest of twigs broken from the tips of tree branches, glued together with saliva and attached to inside wall of a chimney.

Both sexes are involved in nest construction and alternate incubating the eggs for 18 to 19 days, when the young begin to hatch. Their parents catch flying insects on the wing to feed them until the birds fledge from the chimney about 30 days after hatching. The young are able to climb out of the nest after just a few days, and they exhibit preening behavior even before their feathers emerge.

By the time they are 8 or 10 days old, the babies’ feathers begin to unfurl. By 15 to 17 days of age, their eyes begin to open. Soon, most of the flight and body feathers will be unfurled, but the feathers around the face and head will stay in sheath for several days, giving the birds a frosty-faced appearance. By the time chimney swifts are 21 days old, they will cling tightly to the nest or chimney wall, rear back, and flap their wings furiously until they are panting and out of breath. At 28 to 30 days after hatching, young swifts will leave the safety of their chimney nests for their first flight. Once an entire brood has fledged, they will fly with their parents in slow, noisy parades around the area of the nest site in search of food.

The young will return frequently to the roost during the first few days, but will soon begin to visit other roosts in the area. At the end of the breeding season, the swifts’ communal instincts peak prior to fall migration. They congregate in flocks of hundreds and even thousands at suitable roost sites. Although chimney swifts can withstand a few early cool snaps, they will usually ride south on the first major cold front that blows through in the fall.

What Happens if they are already in my chimney?

If they are in your chimney, there is nothing you can do until they have vacated the premises. They are protected under the 1918 Migratory Bird Act. There is a fine of $15,000 for every bird or egg harmed. Once they have departed, it’s a great time to get your chimney inspected, swept (if needed) and install a chimney cap so you do not have them again next summer!
