Blue-Winged Teal 24 Cinnamon Teal 25 Green-Winged Teal 26 Wood Duck 28 students study waterfowl anatomy, habitat, and wildlife conservation. They then articulate composition, migration pathways, and breeding ground origin. There are differences, also, in levels of shooting pressure and harvest. This is a list of the bird species recorded in the archipelago of Puerto Rico which consists of the main island of Puerto Rico, two island municipalities off the east coast (Vieques and Culebra), three uninhabited islands off the west coast (Mona, Monito and Desecheo) and more than smaller cays and avifauna of Puerto Rico include a total of species, of which .
Nearly all drakes lose their bright plumage after mating, and for a few weeks resemble females. This hen-like appearance is called the eclipse plumage. The return to breeding coloration varies in species and individuals of each species. Blue-winged teal and shovelers may retain the eclipse plumage until well into the winter. Blue-winged teal use and maintain a relatively high rate of fidelity to migratory corridors specific to two primary breeding populations, with only % crossover between corridors reported during fall migration. The eastern migratory corridor (EMC) extends from Manitoba and Minnesota through Florida terminating in the Caribbean and.

Certain physio logical parameters were followed in wild hens during all periods of the reproductive cycle. For comparative purposes, some additional information was collected on birds in fall.

While the increase of Blue-winged Teal throughout the Pacific Northwest has been documented, little effort has been made to correlate these trends with those of the Cinnamon Teal in the same area. This paper stems from an overall comparative study made of these teal breeding in eastern Washington.

Blue-winged Teal males were abundant in the vicinity and according to Connelly (A Comparative Study of Blue- winged Teal and Cinnamon Teal Breeding in Eastern Washington. M.S. thesis, Washington State Univ., Pullman, Washington, ), the more aggressive Blue-winged Teal could dom- inate Cinnamon Teal, particularly in certain habitats.

The Green-winged Teal (known as Common Teal in English-speaking parts of Eurasia) is currently considered a single species by the AOU, but two subspecies are distinctive in adult male plumage and are split into two species by many authorities.

Blue-winged teal and shovelers may retain the eclipse plumage until well into the winter. Identification is Important. Identifying waterfowl gives many hours of enjoyment to millions of people. This guide will help you recognize birds on the wing—it emphasizes their fall and winter plumage patterns as well as size, shape, and flight characteristics.

A closer relationship between the Blue-winged Teal and South American Cinnamon Teal suggests two independent colonizations of North America: one ∼95 ybp giving rise to A. septentrionalium in western North America and another ∼65 ybp giving rise to the Blue-winged Teal in central and eastern North America, followed by subsequent.

Snow goose (Anser caerulescens) counts were combined with Ross's goose (A. rossii) counts in the surveys and registered as ‘light’ goose (Table 1). Suggested Citation: Olson, S. Compiler. Pacific Flyway Data Book, U.S. Department of Interior, Fish and Wildlife Service, Division of Migratory Bird.

Inblue‐winged‐cinnamon teal abundance for all western states was estimated atbirds, which was % above the ‐ average (, birds). Green-winged teal feed on seeds of sedges, smartweeds, pondweeds, grasses, aquatic insects, mollusks, crustaceans and tadpoles found while foraging in and adjacent to mudflats or while dabbling in shallow water.

So G would allow for blue or purple wings, but only having g will make a green fairy. A pure-breeding blue winged fairy mates with a purebreeding green winged fairy and have 8 little fairy babies.
The offspring then mate among themselves and produce 9 blue winged, 4 green winged, and 3 purple winged fairy babies.

This is still an important breeding area for pin- tails, redheads, cinnamon teal (Querquedula cyancptera), and others. A large percentage of the birds raised here follow lanes of travel westward to the Pacific flyway, but it is noteworthy that there are at least three routes that leave this area in an easterly or north- easterly direction.
