Purple-crested Turaco

Purple-crested Turaco

Gallirex porphyreolophus

A bulky, iridescent bird clad in deep purple, blue, green, and olive washed with pink. It clambers acrobatically through riverine woodland and savanna thickets. In flight it explodes from the canopy with distinctive deep red panels in the wings. It produces a distinctive croaking “khoh-khoh-khoh-khoh….” that gets progressively louder before suddenly stopping. The similar Ross’s Turaco differs from Purple-crested Turaco by being darker overall and having a red crest and yellow face.

Oriental Skylark

Oriental Skylark

Alauda gulgula

Chunky brown songbird with a weak crest, typically found on the ground in open fields and meadows. Darker above than below, with fine black streaking on the chest and light chestnut ear coverts with dark border. Very similar to Eurasian Skylark, with which it shares much of its range, but Oriental has buffy, not white, outer tail edges and trailing edge of wing. Breeding males “skylark,” singing a series of variable notes while hovering high above the territory.

Western Meadowlark

Western Meadowlark

Sturnella neglecta

Streaked brown above and yellow below with distinctive black "V" on breast. In flight, short wings and spiky tail with white outer feathers are apparent. Breeds in fields and grasslands throughout much of western North America, regularly as far east as Michigan. Winters in a wider range of open habitats, even agricultural fields and roadsides. Extremely similar to Eastern Meadowlark and best distinguished by voice: listen for musical gurgling song and "chuk" calls. In winter, plumage looks paler and more washed-out than Eastern Meadowlark, with a less contrasting head pattern. Western is also more likely to be in flocks and areas with shorter grass (less pristine, extensive grasslands).
