Historical breeding records of four alcids
in British Columbia and southeastern Alaska, 1858-1910.
(12) Species affected by this ongoing oiling event are the same as those affected during actual coastal oil spills in California (eg, alcids
, grebes, loons, diving ducks, procellarids, and pelicans).
Tubenoses (Procellariiformes), in particular, seem to be prone to light attraction, although other taxa of seabirds and coastal birds that are primarily nocturnal at terrestrial nesting areas or are migrating at night also may be attracted in numbers (e.g., shorebirds, nocturnal alcids
Locally, we lose terns, gannets, sea ducks, loons and various species of alcids
- small, penguin-like species of northern waters that include puffins, murres and razorbills.
A total of 17 different groups of seabirds were taken into account, including: loons, grebes, fulmars and petrels, shearwaters, pelicans, cormorants, shorebirds, gulls and kittawakes, terns, skimmers, and alcids
. When species were uncertain and/or categorized as threatened/endangered, their presence (and possibly identification) was also recorded in the database (Bearzi and Saylan 2008).
Oystercatchers; Ibisbill; Avocets and Stilts; Pratincoles; Plovers and Lapwings; Gulls and Turns; Skuas and Jaegers; Skimmers; Alcids
; Loons; Sandgrouse; Olive Warbler and Solitaires; Pigeons and Doves; Parrots and Macaws; Cockatoos; Lories and Lorikeets.
But murrelets are alcids
, members of a family of birds that includes puffins and murres.
Identify at a glance and count thousands of "USDAs" (unidentified small dark alcids
) in flocks flying, sitting on the water, or diving.
However, sequence divergence between species of guillemots for this portion of the control region is similar to that for cytochrome b (Table 2), which has a substitution rate of approximately 2%/million yr in alcids
and other birds (Friesen and Anderson 1997; Friesen et al., unpubl.).
The book is organized by bird family: you'll find separate sections for tubenoses (albatrosses, fulmars, shearwaters, petrels), pelican-like birds, gull-like birds, phalaropes, and alcids
. Maps show distributions; illustrations help you understand bird behavior.
