Smithsonian scientists track endangered bird through its annual cycle

To fully know a species and develop sound conservation efforts, its full life cycle must be understood. But tracking small migratory birds for thousands of miles has proven challenging, if not impossible, in the past. However, using new and minute technology...

Avian malaria affects lekking behaviour of blue-crowned manakins

This research shows the effects of avian malaria, caused by the infection of protozoans of the genus Plasmodium on the social behavior of Blue-crowned manakins. The birds of this species are well-known for holding exhibitions of dances to females during...

Gut microbiota of migratory passerines during stopover

Studies from mammalian systems have highlighted an important role of the gut microbiota in regulating host digestion, metabolism, and immune function; however the makeup and impacts of gut microbiota in avian gastrointestinal tracts is poorly known.

Comparing geolocator and high-precision GPS data

Few recent technologies have been embraced by the ornithological community as rapidly as solar geolocation tracking devices. Although the first and rather large ‘geolocators’ became available more than two decades ago, with their recent miniaturization...

ORCiD now mandatory for submitting authors

From March 2016, it is mandatory for the submitting author to provide an Open Researcher and Contributor ID (ORCiD) via our ScholarOne system. Co-authors and reviewers are strongly encouraged to also connect their ScholarOne accounts to ORCiD...

Directed flight and optimal airspeeds in gulls

Diagnosing in-flight adjustment to wind by birds is challenging, since they may follow landmarks, take detours, soar in thermals or become wind drifted. Gulls are noted opportunists and flight generalists...

Evaluation of two methods for peripheral body temperature measurement

Body temperature is a key physiological property of any animals, and its measurement is thus a valuable tool in ecological and physiological studies. In birds, variation in body temperaturer has been related to a range of parameters...

Millions of mirrors - Iridescent coloration in birds

Like the rainbow shimmer on a soap bubble, the blue color of this male tree swallow (Tachycineta bicolor) feather is iridescent. Light reaching the feather is reflected by its microstructure like a myriad of small mirrors, making it look very bright...

Revealing the migration and winter movements of Swedish Red-necked Phalaropes

Ever since I first visited Ammarnäs in Swedish Lapland in 2007, Red-necked Phalaropes captured my special interest. Well-known for their reversed sex roles, their pelagic lifestyle outside the breeding period has hampered the study of their non-breeding biology...

Using drones to monitor bird nests

In late winter 2013/14 the crow fieldwork crew of the Wolf Lab at the Evolutionary Biology Centre in Uppsala, Sweden, started planning the next field season. The goal was to sample two dozen hooded and carrion crow nestlings from sites in Sweden and Germany...
