The eagles are flying to Maine's remote rocky islands where they have been raiding the only known nesting colonies of great cormorants
in the US.
The present results, together with those of relevant previous studies, strongly suggest an association between these pollutants and thyroid lesions in the great cormorant
This result corroborates earlier findings with Flightless Cormorants, Double-crested Cormorants (Hennemann 1984), Little Cormorants (Microcarbo niger, Winkler 1983) and Great Cormorants
Nine HPAI viruses (H5N1) were isolated in 2009 and 2 were isolated in 2010 from great cormorants
(Phalacrocorax carbo), brown-headed gulls (Chroicocephalus brunnicephalus), great blackheaded gulls (Ichthyaetus ichthyaetus), great-crested grebes (Podiceps cristatus), and bar-headed geese (Anser indicus) and serotyped as described (3).
We obtained 224 great crested grebes (Podiceps cristatus), 16 great black-headed gulls (Larus ichthyaetus), 15 brown-headed gulls (Larus brunnicephalus), 9 bar-headed geese (Anser indicus), 5 ruddy shelducks (Tadorna ferruginea), 3 great cormorants
(Phalacrocorax carbo), and 1 common coot (family Rallidae) (Figure 1).
