The barn swallow will mob intruders such as cats or accipiters that venture too close to their nest, often flying very close to the threat. [60] Adult barn swallows have few predators, but some are taken by accipiters, falcons, and owls. Brood parasitism by cowbirds in North America or cuckoos in Eurasia is rare. [6] [37]
North of the Missouri River, the state is primarily rolling hills of the Great Plains, whereas south of the Missouri River, the state is dominated by the oak-hickory Central U.S. hardwood forest. Some of the native species found in Missouri are included below. [1] [2]
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.
Flamingos are gregarious wading birds, usually 3 to 5 feet (0.9 to 1.5 m) feet in height, found in both the Western and Eastern Hemispheres. Flamingos filter-feed on shellfish and algae. Their oddly shaped beaks are specially adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down.
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]
Mud-nesting species in particular are limited in areas of high humidity, which causes the mud nests to crumble. Many cave-, bank-, and cliff-dwelling species of swallows nest in large colonies. Mud nests are constructed by both males and females, and amongst the tunnel diggers, the excavation duties are shared, as well.
The western meadowlark is the state bird of Kansas. This list of birds of Kansas includes species documented in the U.S. state of Kansas and accepted by the Kansas Ornithological Society (KOS). As of January 2022, there are 483 species included in the official list. [1]
The organ pipe mud dauber, one of many mud daubers in the family Crabronidae, builds nests in the shape of a cylindrical tube resembling an organ pipe or pan flute. Common sites include vertical or horizontal faces of walls, cliffs, bridges, overhangs and shelter caves or other structures. Mud nest of an unidentified mud dauber in Bhopal, India
