Palm Warbler

Scientific Name: Dendroica palmarum

Population Estimate: 20M

Range / Habitat: Breeds in bogs in throughout Canada. Winters in the southeast US coast, Caribbean Islands and coastal parts of eastern Mexico, Belize and eastern Central American, where it is almost always found on or underneath palm trees.

Field Notes: Small songbird bright yellow undertail and distinctive habit of wagging tail constantly. Underparts yellow, back brown, no wing bars. Frequently vocalizes as a single cheep. In breeding plumage, bright rufous cap, yellow supercilium, and rufous streaks on breast. In basic plumage, dull yellow supercilium remains and there may be faint streaks left on the breast. Yellow Warbler is the only other New World warbler with rufous streaks on chest, but has a plain head. Likewise, Prairie Warbler wags tail constantly but has olive cap and black streaking on chest.

Personal Notes: Our most common visitor in the palms outside our beach-front casitas in Tulum and Ambergris Caye. We have also seen this bird in breeding plumage in late spring in Cancun, Mexico and in migration in Minnesota.

Rose-breasted Grosbeak





Scientific Name: Pheucticus ludovicianus

Population Estimate: 4.6M

Range / Habitat: The breeding range of the rose-breasted grosbeak extends from British Colombia in western Canada to the eastern United States. In winter, this species migrates to the southern United States, the Caribbean, Mexico, Colombia, Venezuela, Ecuador and Peru. It can also sometimes be found as a vagrant in Greenland and parts of Europe.

Field Notes:
The Rose-breasted Grosbeak (Pheucticus ludovicianus) is a large insect-eating songbird in the cardinal family (Cardinalidae). It is primarily a foliage gleaner. The rose-breasted grosbeak (Pheucticus ludovicianus) is a medium-sized, stocky songbird with a beautiful, bold plumage which varies greatly between the sexes. The male rose-breasted grosbeak has gained the name ‘cut-throat’ from its distinctive breeding plumage, which has a vivid pink-red triangle on the breast, strongly contrasting with the black upperparts and white underparts.

Muscovy Duck


Scientific Name: Cairina Moschata

Population Estimate: 50K to 500K

Range / Habitat: The Muscovy Duck (Cairina moschata) is a large duck native to Mexico, Central, and South America. Small wild and feral breeding populations have established themselves in the United States, particularly in the lower Rio Grande Valley of Texas, as well as in many other parts of North America, including southern Canada. Feral Muscovy Ducks are found in New Zealand and have also been reported in parts of Europe.

Field Notes: The Muscovy Duck (Cairina moschata) are a large duck, with the males measuring about 76 cm in length, and weighing up to 15 pounds. Females are considerably smaller, and only grow to 7 pounds, roughly half the males' size. The bird is predominantly black and white, with the back feathers being iridescent and glossy in males, while the females are more drab. The amount of white on the neck and head is variable, as well as the bill, which can be yellow, pink, black, or any mixture of these. They may have white patches or bars on the wings, which become more noticeable during flight. Both sexes have pink or red wattles around the bill, those of the male being larger and more brightly colored.

It is found from the coastal areas of California through much of the interior western United States and along the Gulf of Mexico as far east as Florida, then south through Central America and the Caribbean to northwest Brazil southwest Peru,east Ecuador and the Galápagos Islands.

Field Notes: The Black-necked Stilt (Himantopus mexicanus) is often treated as a subspecies of the Common or Black-winged Stilt, using the trinomial name Himantopus himantopus mexicanus. Adults have long pink legs and a long thin black bill. They are white below and have black wings and backs. The tail is white with some grey banding. A continuous area of black extends from the back along the hindneck to the head. There, it forms a cap covering the entire head from the top to just below eye-level, with the exception of the areas surrounding the bill and a small white spot above the eye. Males have a greenish gloss to the back and wings, particularly in the breeding season. This is less pronounced or absent in females, which have a brown tinge to these areas instead. Otherwise, the sexes look alike.

They are seen in a variety of different habitats from wet regions such as rainforests, to drier areas such as cactus savannahs. Their breeding season is usually in the spring, starting in February and ending in the summer (in June and July in most areas). After breeding, the female will lay an average of three to four white eggs.

Field Notes:  The White-fronted Amazon (Amazona albifrons) also known as the White-fronted Parrot, or adopted slang term Spectacled Amazon Parrot is a Central American species of parrot. They have mostly green plumage with some blue colouring on their outspread wings. They have bright red coloring around their eyes (in some individuals almost like spectacles) and blue coloring behind the patch of white on their foreheads. Together with the Red-spectacled Amazon and the Yellow-lored Amazon, it is the only Amazon species in which adult males and females easily can be distinguished by external appearance (sexual dimorphism). Males have bright red feathers on their "shoulders" (alula), while females have green "shoulders". Juveniles have pale grey irises and less red on their face and the white area is replaced with a smaller yellowish area.
