NSO journals in Covid-19 times

As the world grapples with COVID-19 we write, above all, to wish you and those close to you continued good health.  These are uneasy times and we wanted to let you know that the editorial office of the Nordic Society Oikos (NSO) is open (online and virtually).

Transparent Peer Review

We are very happy to announce that Journal of Avian Biology is participating in a pilot on transparent peer review.

House finches add cigarette butts to their nests to avoid ectoparasites

House finches in Mexico City break down cigarette butts and use them to line their nests. This may be a response to tick infestation, as these blood sucking parasites are repelled by substances such as the nicotine contained in the discarded butts, but can we be certain?

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.

Editor's Choice: A test for repertoire matching in eastern song sparrows

By critical and elegant playback experiments the authors of this highly interesting study demonstrate that vocal signalling behaviour differs fundamentally between a western and eastern population of the same species (song sparrow, Melospiza melodia).

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...

Editor's Choice: Is the denser feathers in grey Tawny owls an adaptation to cold environments?

Surviving in cold environments at high latitudes puts a great premium on behavioral, morphological and physiological adaptations to conserve heat. One of the most prominent adaptations is the plumage of birds which when fluffed may form...

Impacts of nest predators and weather on reproductive success in American redstarts

Understanding the population ecology of different phases in the complex annual cycle of long-distance migratory birds, and determining the importance of winter vs summer vs migration impacts, and their carry-over effects, on population dynamics...

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...

Nesting success of native and introduced forest birds on the island of Kaua‘i

When I signed up to move to Kaua‘i and began an M.Sc. project studying the nesting biology of two recently-listed endangered forest bird species, the ‘Akikiki and ‘Akeke‘e, I knew I was in for a rewarding challenge!

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...

Editor's choice - Common loon parents defend chicks according to both value and vulnerability

Breeding is obviously a very important part in the life of organisms. However, the effort put into breeding need to be traded off against effort put into defense of the parents’ own soma. One often neglected part of parental effort is to protect young...

Editor's Choice: Breeding season weather determines long-tailed tit reproductive success

It is common that avian scientists working with breeding biology claim that weather has a large impact on breeding productivity although this is usually just a “feeling” and seldom formerly tested.

Editor's Choice: Consistent foraging strategies in individual seabirds

New tracking techniques have opened up possibilities to record individuals on repeated foraging flights and investigate to what degree they show individuality in their behaviour.

Editor's Choice: Seasonal mortality and sequential density dependence in a migratory bird

This study compares annual survival patterns of red knots Calidris canutus islandica between two periods, when winter food at the Wadden Sea was reduced by cockle harvesting and in following years when cockle-dredging was stopped...
