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...

Merry Christmas and Happy New Year!

Journal of Avian Biology wish all its readers, authors, reviewers and editors a relaxing and enjoyable holiday season. We hope that you all get some well-deserved rest together with family and friends.

Automated tracking of wild hummingbird mass

In this study the authors examine the use of automated collection of hummingbird mass data using low-cost, low-power radio frequency identification (RFID) technology. In a field study in southern Ontario, wild hummingbirds were captured, subcutaneously implanted with...

New impact factor and other numbers

About two weeks ago Thomson Reuters published their annual Journal Citation Report. For us editors this is a day of excited anticipation – even though most of us agree that this measure is far from perfect, it...

Nuthatch fecundity improves with mountain pine beetle outbreak

Food pulses during the breeding season can reduce competition for food and increase fecundity. But, for cavity-nesting birds that excavate new nest cavities, a reproductive cost associated with excavation, may limit the reproductive response to food pulses.
