The barn swallow (Hirundo rustica) is the most widespread species of swallow in the world, occurring on all continents, with vagrants reported even in Antarctica. [ 2 ] [ 3 ] It is a distinctive passerine bird with blue upperparts and a long, deeply forked tail.
The typical nest is a grass or feather-lined deep closed mud bowl with a small opening at the top, [12] but many Asian house martins leave the top of the nest open. [ 20 ] [ 21 ] [ 22 ] David Winkler and Frederick Sheldon believe that evolutionary development in the mud-building swallows, and individual species follow this order of construction.
Michigan's 20 largest inland lakes. This is a list of lakes in Michigan. The American state of Michigan borders four of the five Great Lakes. The number of inland lakes in Michigan depends on the minimum size. There are: 62,798 lakes ≥ 0.1 acres (0.00040 km 2) [1] 26,266 lakes ≥ 1.0 acre (0.0040 km 2) [1] 6,537 lakes ≥ 10.0 acres (0.040 ...
Otherwise, they will build a new nest on top of the old one which puts the nest even closer to the entrance hole which gives predators a better chance at doing damage. On Sunday, June 9 at 7:30 a.m.
They have a slender streamlined body, long pointed wings and a short bill with a wide gape. The feet are adapted to perching rather than walking, and the front toes are partially joined at the base. Eight species have been recorded in Michigan. Cliff swallow, Petrochelidon pyrrhonota; Bank swallow, Riparia riparia; Barn swallow, Hirundo rustica

It is much more urban than the barn swallow, and will nest even in city centres if the air is clean enough. [14] It is more likely to be found near trees than other Eurasian swallows, since they provide insect food and also roosting sites. This species does not normally use the reed-bed roosts favoured by migrating barn swallows. [16] [17]
The cliff swallow or American cliff swallow (Petrochelidon pyrrhonota) is a member of the passerine bird family Hirundinidae, the swallows and martins. [2] The generic name Petrochelidon is derived from the Ancient Greek petros meaning "stone" and khelidon (χελιδών) "swallow", and the specific name pyrrhonota comes from purrhos meaning "flame-coloured" and -notos "-backed".
