(1,2) Reference values for cardiac width have been reported for several avian species, including psittacine birds, (3-3) falconiform species, (6-9) screech owls (Otus asio), and Canada geese (Branta
The occurrence and performance of leucistic barnacle geese Branta
Young footballers of this age have all the prerequisites for further development of higher levels of co-ordination (Branta
, Haubenstricker&Seefeldt, 1984; Ford et al., 2010).
Until the end of the 1980s, the Barnacle Goose (Branta
leucopsis) was an extremely rare migrating species in the Russian part of the Gulf of Finland, but in recent years it has become one of the mass migrants there.
Yn y gaeaf, fe fydd tua tair mil o wyddau duon (Branta

In previous studies, numerous avian species like European starlings (Sturnus vulgaris), house sparrows (Passer domesticus), feral pigeons (Columba livia), red- winged blackbirds (Agelaius phoeniceus), common grackles (Quiscalus quiscula), brown headed cowbirds (Molothrus ater), American kestrels (Falco sparverius), Canada geese (Branta
canadensis), mallards (Anas platyrhynchos), cedar waxwings (Bomby cillacedrorum) and yellow-headed blackbirds (Xanthocephalus xanthocephalus) also showed the similar results and suppress the depredations when seeds treated with anthraquinone and methylanthranilate were provided to the birds (Cummings et al., 1998).
America, the Pacific or black brant (Branta
bernicla nigricans) found along the Pacific Coast, and the American or light-bellied brant (Branta
bernicla hrota) found on the Eastern Seaboard.
The waterfowl included American black duck (Anas rubripes), Canada goose (Branta
canadensis), mallard (Anas pkityhynchos), and wood duck (Aix sponsa).
We observed during high tide eared grebes (juveniles, adults), snowy egrets (juveniles), brant goose (Branta
bernicla, adults), marbled godwit (Limosa fedoa, adults) and snowy plovers (Charadrius alexandrines, adults) foraging in the wetland.
Preliminary results show that a putative source of fecal contamination, resident Canada geese (Branta
canadensis), can be distinguished apart from human contamination based on antibiotic resistance pattern disparities.
