Black-collared Swallow

Rather large sparrow with flat head and long bill. Dull brownish overall with darker streaks on back; subtle head pattern with slightly darker crown and eyeline. Primarily a Mexican species with two populations, both of which barely enter the U.S.; western birds brighter than eastern birds. Prefers grasslands with some shrubs. Shy, but perches conspicuously when singing. Similar to Cassin's Sparrow; note flatter head, longer bill, lack of eyering, and voice. Gives a series of sharp varied chips and a fast trill; much different than Cassin's sweet song.

Large striking flycatcher of tropical and subtropical forest and woodland; also in semi-open areas with taller trees. Perches mainly at mid-upper levels, often in the canopy. Fairly common in most areas, but uncommon and local in West Mexico. Told from widespread Great Kiskadee, which prefers more open and less wooded habitats, by dull olive upperparts (lacking the bright rusty wings and tail of kiskadee) and stouter bill, with a more strongly arched ridge along the top. The two species sound quite different.

Brown lapwing with a gray head and neck, bright yellow bill, and a white belly and gray breast separated by a dark breast band. When in flight, note striking black primary feathers and white secondaries, as well as a white rump and dark tail. Gregarious, usually seen in loose small flocks, sometimes with other lapwings. Inhabits cultivated wetlands and marshy areas, feeding mainly on insects, worms, and crustaceans. Gives grating, piping screams.
