Seasonal variation in CREB expression in the hippocampal formation of first-year migratory songbirds: Implications for the role of memory during migration

http://americanornithologypubs.org/doi/abs/10.1642/AUK-16-133.1

"These results suggest that young migratory birds may store relatively little spatial information during migration, particularly until they reach their wintering area and their global navigational map is more fully developed."

Article: Tackling the Threat of Lead Poisoning Posed by Game Meat

http://www.selectscience.net/selectscience-interviews/tackling-the-threat-of-lead-poisoning-posed-by-game-meat/?artID=42795

Paper: Detection of lead nanoparticles in game meat by single particle ICP-MS following use of lead-containing bullets

http://sci-hub.cc/10.1007/s00216-016-0132-6

"In addition to dissolved lead in meat that originated from particulates, the presence of lead nano particles (PbNPs) in game meat represents a hitherto unattended source of lead with a largely unknown toxicological impact to humans."

"PbNPs could be detected in game meat and their size distribution determined. To the best of our knowledge, this is the first time that the occurrence of nanometer-sized lead particles in bullet-shot game is reported."

"...since metallic Pb dissolves in biological systems over time, there is a probability for larger metallic Pb fragments to partly dissolve on their way through the gastrointestinal tract and reach the size of nanoparticle that could penetrate the membranes and enter the blood system. However, independently of the origin of the PbNPs, the distribution and later dissolution of the PbNPs in the body are of toxicological interest, especially if the absorbed PbNPs can pass through cell barriers."

Are birds cut out for city living?

https://www.washingtonpost.com/news/animalia/wp/2017/01/25/are-birds-cut-out-for-city-living/?utm_term=.cd9a8fe35b06&wpisrc=nl_animalia&wpmm=1

Paper: Breeding Dispersal by Birds in a Dynamic Urban Ecosystem

http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0167829

"Knowing that individual avoiders seek distant forests when the landscape they inhabit, and not just their immediate territory, is developed suggests that the spatial extent of a neighborhood's effect is greater than its immediate developed footprint. Moreover, the apparent inability of avoiders to improve their reproductive fitness by leaving changing lands suggests that the ecological consequences of developments are far-reaching and long lasting."
