Inventory of wildlife use of mortality pits as feeding sites: implications of pathogen exposure
To better understand the use of mortality pits by wildlife and possible pathogen dissemination from the resulting wildlife contact in these areas, we used 8 camera traps on 4 mortality pits in Colorado from June to December 2014 to create a species ...

Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Effects of vehicle speed on flight initiation by Turkey vultures: implications for bird-vehicle collisions. [PDF]
The avoidance of motorized vehicles is a common challenge for birds in the modern world. Birds appear to rely on antipredator behaviors to avoid vehicles, but modern vehicles (automobiles and aircraft) are faster than natural predators.

Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Two new reports of leucistic birds from Mexico
We present two new records of leucism in two bird species from two locations in Mexico. First, we report one leucistic Barn Swallow (Hirundo rustica); the individual was a nestling observed between 15 July and 6 August 2010, in a suburban area of ...

Introduced wild pigs affect the foraging ecology of a native predator as both prey and scavenger
Introduced species can disrupt trophic interactions by acting as novel predators, prey, or scavengers. Predicting the impacts of these disruptions can be integral to the conservation of native species and the maintenance of ecological function, but is challenging, especially for species involved in multiple trophic interactions.

As carrion feeders competing for a limited and ephemeral resource, avian scavengers are ideal model organisms to study mechanisms of niche partitioning.

Scavenger dynamics at cervid carcasses in a chronic wasting disease endemic zone
This study quantifies scavenger species use of 20 deer carcasses in a chronic wasting disease endemic zone, including species‐specific time spent on carcasses and carcass materials consumed. We discuss the implications of our results for scavengers' roles in potential disease transmission dynamics.

Similarities between New World and Old World vultures have been interpreted to reflect a close relationship and to suggest the inclusion of both in Accipitridae (Falconiformes).
