The minute hermit is one of the world's smallest birds. [5] It is 8.4 to 9.2 cm (3.31 to 3.62 in) long and weighs 1.8 to 2.7 g (0.06 to 0.10 oz). The male has dark iridescent green upperparts and a dark brown throat. The female's underparts are reddish orange. Both sexes have a black "mask" and a pale supercilium and malar stripe. [6]
The calliope is the smallest breeding bird found in Canada and the United States. [3] [4] An adult calliope hummingbird can measure 7–10 cm (2.8–3.9 in) in length, span 11 cm (4.3 in) across the wings and weigh 2 to 3 g (0.071 to 0.106 oz). [4] Calliope hummingbirds have glossy green on the back and crown with white underparts. [3]
There are an additional 146 species whose presence in the United States is only within one or more U.S. territories; some of those species have become extinct. The total number of bird species on the list is 1267 (i.e. the 1120 bird species found in the 50 states and District of Columbia, plus the 146 species found only in the U.S. territories).
The pygmy falcon is the smallest bird of prey on the African continent, and among the smallest raptors on earth; only the Asian falconets (of the genus Microhierax) are smaller, weighing roughly 30-40 grams less and measuring about 5 cm shorter from head-to-tail.
The bee hummingbird has also been described as the smallest dinosaur. [7] This characterization is based upon the recognition that birds are, in fact, a living form of theropod dinosaurs (or, strictly speaking, avian dinosaurs), [8] and no smaller bird or non-avian dinosaur has been found in the fossil record.

Grebes are small to medium-sized diving birds. They breed on fresh water, but often visit the sea when migrating and in winter. They have lobed toes and are excellent swimmers and divers; however, their feet are placed far back on their bodies, making them quite ungainly on land. Atitlan grebe, Podilymbus gigas (E) EX E
