'Urban Raptors': Q&A with authors of book on ecology and conservation of city-dwelling birds of prey

It's go time for Hawaiian bird conservation, and luckily there's a playbook

A flicker of hope: Genomic data distinguish Northern Flicker taxa despite low levels of divergence

http://americanornithologypubs.org/doi/full/10.1642/AUK-18-7.1


Phenotypic variation and geographic distribution of 3 taxa in the Northern Flicker complex: Gilded Flicker (purple), Red-shafted Flicker (red), and Yellow-shafted Flicker (yellow). The orange region of the map shows the approximate location of the hybrid zone between Red-shafted and Yellow-shafted flickers in the North American Great Plains. Diamonds represent sampling locations.

When you're a sitting duck, you learn to adapt

Paper: Common Loons respond adaptively to a black fly that reduces nesting success

http://americanornithologypubs.org/doi/full/10.1642/AUK-17-239.1?code=coop-site


Sites with high numbers of black flies (yellow stars), and where nest abandonments (red dots) and successful hatches (black dots) occurred during 3 years with severe black fly outbreaks (2011, 2014, and 2017). Green line traces the path of the largest source of flowing water, the Wisconsin River, which is dammed at 4 points.

Owls see as humans do

This montage illustrates a barn owl (Tyto alba) watching a monitor displaying a paradigm which tests behavioral and neural responses to figure-ground segregation. The paradigm consists of a target dot appearing inside the borders of the site's receptive field (figure, represented by the dashed red circle), and moving to the right (denoted by the gray arrow), surrounded by dots-array (ground). The colors of the arrows represent 3 types of movement tested: (1) magenta relates to condition where 100% of the circles moved 1350 upwards; (2) green relates to condition where 70% of the circles moved 1350 upwards; (3) blue relates to condition where 50% of the circles moved 1350 upwards. In behaving barn owls the coherency of the background motion modulates the perceived saliency of the target object, and in complementary multi-unit recordings in the Optic Tectum, the neural responses were more sensitive to the homogeneity of the background motion than to motion-direction contrasts between the receptive field and the surround.

It All Started With a Few Trout. Now Yellowstone's Iconic Birds Face 'Collapse.'
