Euler's Flycatcher

This unmistakable warbler is found in canyons and mountainous areas with oaks and pines. Striking plumage: black with large white wing patch and red belly. Tail is often fanned and flashed while foraging, revealing bold white outer tail feathers. Very active, usually flitting around in the lower to mid-levels of trees. Listen for a musical warble with repeated “chewee” notes. Call is similar to Pine Siskin but less wiry. Primarily a Mexican species, occurring as far south as northern Nicaragua. Breeding range barely extends into the southwest U.S.

A small, fast-flying petrel with long narrow wings and bright white underparts. Found singly or in loose aggregations, well offshore in warmer Pacific waters, mainly from March to August. Flight varies from low and weaving, into the wind, to high and arcing across the wind. Note gray cap and upperparts with dark M pattern across upperwings and dark tail tip. Underparts are white with very narrow black margins to wings. Many birds off Mexican coast are in wing molt.

Small hummingbird with an exceptionally long tail. Green overall with a fairly short, slightly decurved bill. The male’s long tail is striking. Sexes similar but females are more spotted below and have a shorter tail. Could be confused with Long-tailed Sylph, but the trainbearer occurs in dry, scrubby, open habitats, not in forests. Compare with very similar Green-tailed Trainbearer; Black-tailed has a longer, more decurved bill, a longer tail that usually looks slightly curved, and is somewhat duller green. Occurs from Colombia to Peru, from around 2,500 to 3,800 m. Occasionally visits feeders, but more often seen feeding at flowering shrubs.
