The Lesser Swallow-tailed Swift, also known as the Mearns's Swift, is a small aerial bird species belonging to the Apodidae family. It is found in the highlands and mountainous regions of southern Mexico, Guatemala, and Honduras, and is also present on the Pacific slope of Costa Rica.
The Lesser Swallow-tailed Swift is a very distinctive bird with its sleek body, long pointed wings, and deeply forked tail. It has a bluish-black coloration on its back and wings, while the underparts are greyish-brown. The sexes are similar in appearance.
This species of swift is known for its highly aerial and acrobatic flight, with impressive aerial maneuvers that include sudden twists, dives, and swoops. They feed on insects in flight, such as flying ants and termites, which they catch with their wide, gaping mouths while in flight.
The Lesser Swallow-tailed Swift is typically found in the forests, especially in the montane cloud forests and pine-oak forests. They nest in colonies in rock crevices or under overhangs of cliffs, usually in areas close to water. Their nests are made of small twigs, moss, grass, and feathers, cemented together with sticky saliva.
This species is not considered threatened at present. However, threats to its habitat through deforestation, mining, and agriculture are causing a decline in their numbers. Conservation measures include the protection of their breeding sites and monitoring of populations.
In conclusion, the Lesser Swallow-tailed Swift is an impressive aerial bird that is a vital part of the montane cloud forest ecosystem. Its unique flying abilities and colony behavior make it a fascinating species to observe. With proper conservation measures and protection, we can ensure the survival of this species, and many others, for generations to come.
