Amazonian Grosbeak

Very large for a hummingbird; size alone separates from many other species. Males and females similar: gray below, dusky-greenish back, brown rump, and large dark tail with prominent white corners. Also note white eyebrow and short white mustache stripe. Male has bright blue throat patch, difficult to see unless the light hits it just right. Uncommon in canyons and mountains with mixed pine-oak forests, primarily in Mexico but barely extending into the U.S. Very similar to Amethyst-throated Mountain-gem, especially if you can’t see the throat color. Blue-throated is slightly larger and paler overall with larger white (not gray) tips on the tail feathers; females are plainer, lacking the buffy tones of Amethyst-throated. Also compare with Rivoli’s Hummingbird, especially females; Blue-throated is shorter-billed and plainer (less speckled) on the underparts.

A stunning long-tailed waxbill with a red bill, mauve cheeks, and a blue rump. The underparts are vibrant chestnut in the male and cream-buff in the female. Pairs are resident in arid thorn savanna and drier woodlands, where they forage on the ground and lower layers of scrub, often in the company of other finches. The species can be secretive, flying quite a distance when flushed. The Black-faced Waxbill is dark like Violet-eared Waxbill, but it has a red rump, a dark mask, and barred wings. The Purple Grenadier lacks mauve cheeks, and its range does not overlap.

Long-winged raptor, often seen in large kettles on migration. Breeds in montane forests, where its strident two-note whistle is often heard. Adult is brown with a spotted belly, a clean white throat bordered by two black streaks and distinct white eyebrow. Juvenile is more extensively white on the head and belly, with brown upperparts sometimes blotched with white. Can be confused with Oriental Honey-Buzzard but head proportionately larger, wings narrower, and barring on the wings weaker.
