'On life support:' Research shows common pesticides starve, disorient birds

http://nationalpost.com/pmn/news-pmn/canada-news-pmn/on-life-support-research-shows-common-pesticides-starve-disorient-birds


A white crested sparrow is seen in this undated handout photo. Research suggests that two of Canada's most commonly used pesticides cause migrating songbirds to lose both weight and their sense of direction. THE CANADIAN PRESS/HO, University of Saskatchewan *MANDATORY CREDIT*


Paper: Imidacloprid and chlorpyrifos insecticides impair migratory ability in a seed-eating songbird

https://www.nature.com/articles/s41598-017-15446-x.epdf

Quotes:

"These results suggest that wild songbirds consuming the equivalent of just four imidacloprid-treated canola seeds or eight chlorpyrifos granules per day over 3 days could suffer impaired condition, migration delays and improper migratory direction, which could lead to increased risk of mortality or lost breeding opportunity."

"Declines in migratory bird populations have been linked to a range of complex factors, including the large-scale application of agricultural pesticides."

"Birds that utilize agricultural landscapes may be exposed to insecticides through consumption of treated seeds, granules, or sprayed soils and prey items. Small migratory songbirds that regularly use farmland habitats as a stopover and refuelling source may be particularly susceptible to exposure and the negative effects of neurotoxic insecticides."

"Organophosphates and neonicotinoids have effects on survival, as well as sublethal neurophysiological and behavioural effects in birds, including impaired thermoregulation and food consumption."

University of Akron Researchers Create New Non-Toxic Pigments Inspired By Bird Feathers (really interesting)

http://wksu.org/post/univeristy-akron-researchers-create-new-non-toxic-pigments-inspired-bird-feathers#stream/0


The arrangement of melanin particles in feathers provides a range of structural colors in birds, from iridescent green of the teal to the shimmering brown of turkeys.

Nano-sized balls of melanin aggregate into clusters called supraballs. Melanin appears black in individual nanoparticles. But altering spacing of the nanoparticles in the ball scatters light to produce a range of colors.

(This work is interesting, but it's based on a very small sample size. It does show the way for much more research.)

Article: Young Bald Eagles Live Life in the Fast Lane

https://www.hakaimagazine.com/article-short/young-bald-eagles-live-life-fast-lane?utm_source=Hakai+Magazine+Weekly&utm_campaign=4df52739e1-EMAIL_CAMPAIGN_2017_09_06&utm_medium=email&utm_term=0_0fc1967411-4df52739e1-121598265

Paper: To migrate, stay put, or wander? Varied movement strategies in bald eagles (Haliaeetus leucocephalus)

https://movementecologyjournal.biomedcentral.com/articles/10.1186/s40462-017-0102-4



Movement strategy classification flow chart



Examples of the four different strategies of movement observed in bald eagles monitored along the north Pacific coast, 2010-2016. Breeders (a) remained near nesting sites year-round, with short distance movements for access to seasonal resources (i.e. autumn). Non-breeding localized individuals (b) engaged in primarily short-distance movements for access to seasonal resources (i.e. spring, autumn) within a distinct range. Non-breeding migratory individuals (c) had directed moves in autumn and spring between distinct summer and winter ranges. Non-breeding nomadic individuals (d) displayed irregular movement patterns with little interannual consistency.



Average distance traveled per day by bald eagles monitored along the north Pacific coast, 2010-2016; data presented by month by a movement strategy, b age class, and c sex class. Migratory birds traveled greater distances per day than any other class. Across all months, immature birds traveled greater distances per day than adults, and males traveled greater distances per day than females.
