What do we really know about the water repellency of feathers?
Journal of Avian Biology, Volume 2024, Issue 11-12, November/December 2024.Feathers are complex integument structures that provide birds with many functions. They are vital to a bird's survival, fundamental to their visual displays, and responsible for the evolutionary radiation of the avian class. Feathers provide a protective barrier for the body; their water repellency is a key feature.

Ibis, Volume 166, Issue 4, Page 1296-1310, October 2024.The over‐exploitation of wild birds and the products derived from them can be a key threat driving changes in bird species richness and abundance. However, inadequate information on harvest levels combined with irregular population monitoring often means that the role of harvesting in population decline is difficult to quantify.

Patterns of energy acquisition by penguins: benefits of alternating short and long foraging trips. [PDF]
, 2004 In some seabirds, foraging trips have been defined as either long or short, with the length of time spent traveling to the foraging area apparently a critical feature in determining foraging trip length.

Ecology and Evolution, Volume 14, Issue 9, September 2024.This study tests whether populations of Black Oystercatchers (Haematopus bachmani) across Alaska, the United States, and British Columbia, Canada, follow patterns of latitudinal gradients in morphology. Specifically, we test for patterns of Allen's and Bergmann's Rules, as well as differences in wing morphology based on migratory strategy.

Eye morphology contributes to the ecology and evolution of the aquatic avifauna
Journal of Animal Ecology, Volume 93, Issue 9, Page 1262-1274, September 2024.Aquatic birds are notable among the global avifauna for living in environments exposed to large amounts of light. Here, I show that eye size strongly predicts key aspects of aquatic bird ecology, including foraging behaviour, diet, height of aerial plunge dives, and depths of underwater pursuit dives. Abstract Aquatic birds are notable among the global

Economical genotyping of little blue penguin (Eudyptula minor) clades from feather-based DNA [PDF]
, 2013 Determination of clade membership is a crucial requirement for many research questions addressing phylogeography, population structure, mating patterns, speciation, and hybridisation.
