Red-legged Honeycreeper


Scientific Name: Cyanerpes cyaneus

Population Estimate: 5M-50M

Range / Habitat: Resident in low altitude forest edge and plantations in southern Mexico and Central America.

Mew Gull


Scientific Name: Larus Canus

Population Estimate: 2.5M - 3.7M

Range / Habitat: The common gull has a wide distribution, breeding throughout temperate and sub-Arctic parts of Eurasia. Two subspecies occur in Europe, the ‘nominate’ race L. c. canus is the subspecies occurring in Britain, extending through north-west Europe and reaching the White Sea in Russia. There is also a subspecies that occurs in North America. In Britain, this species breeds mainly in Scotland

Field Notes: It is generally similar in appearance to the herring gull (Larus argentatus) but is smaller, and has a smaller, thinner bill, a more rounded head and more active flight. The upperwings are pale grey in colour and have black tips featuring white spots known as ‘mirrors’. The white head develops grey streaks in winter and the legs and bill are greenish-yellow. Juveniles are greyish brown with brown upperparts.

Personal Notes:

Yellow-billed Loon

Field Notes: Olive-backed songbird with yellow throat. Males with prominent black mask and white stripe above (as in the photos), females without. Song a repeated "witch-it-ty."

Personal Notes: We first saw this bird on a trip to Rhode Island, to visit Ted and Jo. 

Northern Mockingbird


Scientific Name: Mimus polyglottos

Range / Habitat: Year-round in shrub land throughout the United States and Mexico.

Field Notes: Medium-sized grey songbird with long tail, dark wings with white wing bars, and a black eye stripe. Similar overall appearance to both the Loggerhead and Great Grey Shrike, but the shrikes have slightly different ranges and wide black mask instead of an eye stripe. Townsend's Solitaire is also similar but has a more restricted range, is the same shade of grey all over, and has a white eye ring instead of a black eye stripe.

Personal Notes: It was remarkable to watch and listen to this bird with a seemingly endless array of different melodies.
