Crimson-rumped Waxbill

Male is a fairly distinctive seedeater with yellow belly (sometimes very pale), dark breast and face, and brownish-olive back. Often shows some smudgy dark marks down the flanks. Bill is pale silvery. Female seedeaters are extremely difficult to identify; Yellow-bellied tends to look warmer with yellowish tones on underparts, but many are best left unidentified unless accompanied by a male. Most often found in flocks or pairs in open grassy habitats, sometimes near the edge of forest but also in agricultural areas.

Uncommon flycatcher with a highly restricted range in northern Peru. It is known from white sand forest near Iquitos and from Andean foothills in the vicinity of the cities of Moyobamba and Tarapoto. Plumage is mostly yellowish-olive with a pale bill and eye and yellow fringes to the wing feathers. Very similar to Red-billed Tyrannulet, but usually shows an olive (not gray) crown; voice is a more reliable way to separate the two species. Listen for a high, piping whistle given alone or in pairs. Calls have a rasping quality in the lowland part of the range. Inhabits forest canopy.

Unique: crested head with striking black-and-white pattern unlike any other bird. Primarily a Mexican species, with limited range in the U.S. Found in dry woodlands, especially with mixed oaks and junipers. Feeds on insects and acorns. Small and active; often joins mixed-species flocks with warblers, vireos, and kinglets. Visits feeders.
