Long-term studies of Pigeon Guillemot breeding and prey selection have been conducted by the WIPGRG, with 12 years of observations recorded using a standardized methodology. About. … The Guillemot Reaearch Group is a citizen science organization under the Whidbey Audubon Society. The Person behind; Published; The Idea of bird-lens; Projects; Data protection; Impressum; Photos. Pigeon Guillemot specialized in prey hunting when foraging for its calves, resulting in higher reproductive success, allowing a higher lipid diet to increase further.

There is little information on population trends of Pigeon Guillemot, but numbers appear stable.

Long-term studies of Pigeon Guillemot breeding and prey selection have been conducted by the Whidbey Island Pigeon Guillemot Research Group (WIPGRG), with 11 years of observations recorded using a standardized methodology.

Energy density and variability in abundance of pigeon guillemot prey: support for the quality-variability trade-off hypothesis Summary 1.

Researchers speculated that immediately after the Spill, predators such as river otters and minks preyed more heavily on nesting guillemots due to heavy oiling and subsequent reduction of their customary shellfish prey.


The study in NRAR was modeled after the Whidbey Island program.

Adult Pigeon Guillemot needs about 20% or 90 grams (3.2 oz) of their own weight daily.

Description de l’entreprise Each year the Guillemot Research Group trains volunteers to monitor Pigeon Guillemot's, noting their choice of prey, number of active burrows and breeding success.

Small fish and a variety of other aquatic creatures, including mollusks and crustaceans, make up the Pigeon Guillemot's diet. Data collection procedures, field cards, training, mentoring, and support were provided by WIPGRG.

Pigeon guillemot populations are highly impacted by factors such as oil spills, impacts to nearshore habitats (direct or indirectly), shifting climate regimes causing a shift in available prey, and predation by introduced species (Kreamer, 2012). Additional details regarding the development and …

Pigeon guillemot is part of WikiProject Birds, an attempt at creating a standardized, informative and easy-to-use ornithological resource.If you would like to participate, visit the project page, where you can join the discussion and see a list of open tasks. The quality‐variability trade-off hypothesis predicts that (i) energy density (kJ g − 1 ) and spatial‐temporal variability in abundance are positively correlated in nearshore marine fishes; and (ii) prey selection by a nearshore piscivore, the pigeon guillemot ( Cepphus columba Pallas), is negatively affected by variability in abundance. First, we investigated the role of dietary factors (prey type, quantity of food consumed, dietary fat content, and energy intake rate) in limiting the growth, development, survival, and fledging condition of nestling Pigeon Guillemots. ADULT PREY CHOICE AFFECTS CHICK GROWTH AND REPRODUCTIVE SUCCESS IN PIGEON GUILLEMOTS GREGORY H. GOLET,13 KATHERINE J. KULETZ,1 DANIEL D. ROBY,2 AND DAVID B. The North American Waterbird Conservation Plan estimates a continental population of less than 69,000 breeding birds, rates the species a 13 out of 20 on the Continental Concern Score, and lists it as a Species of Moderate Concern.
