Chestnut-crowned Bush Warbler

Large spiderhunter with yellow eyerings and a similarly-colored tuft on the cheek. Bill is bicolored: pinkish at the base and darker towards the tip. Faint streaking on the throat, slightly longer and more slender bill, larger yellow ear tuft, and slightly narrower eyerings help distinguish it from similar Spectacled Spiderhunter. Forages in upper levels of lowland, foothill, and montane forests. Gives rather dry papery chittering.

Attractive small sparrow endemic to highlands in central Mexico. Favors dense brushy areas and flower banks in pine-oak forest. Often rather skulking, but also curious, popping up to investigate scolding groups of other birds and contributing its sharp, chipping calls to the mob. Usually in pairs, sometimes in small groups, foraging in weedy vegetation, less often on the ground. Note rusty cap, gray face, and bright yellow bib. Lacks white eyebrow of Rufous-capped Warbler, which often occurs in the same areas.

Common and widespread large gull found throughout North America. Adults have a fairly pale gray back, pale eye, and dull pinkish legs. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Usually shows a dull pinkish base to the bill by the first winter, and develops a pale eye by the second winter. Some immature birds can fade to almost white, especially in their first or second summer, but they always show darker wingtips. Occurs inland and along the coast, frequenting fishing boats, beaches, lakes, and landfills. Often forms large flocks with other gulls.
