Fruiting Season Length Restricts Global Distribution of Female-Only Parental Care in Frugivorous Passerine Birds. [PDF]
Food availability is known to influence parental care and mating systems in passerine birds. Altricial chicks make uni-parental care particularly demanding for passerines and parental investment is known to increase with decreasing food availability.

Provenance does matter: links between winter trophic segregation and the migratory origins of European robins [PDF]
Amongst migratory species, it is common to find individuals from different populations or geographical origins sharing staging or wintering areas.

Vatka et al. investigated how changing food abundance affects evolutionary potential of offsprings' body size traits in two woodland passerines. Food availability increased over the 25‐year‐long study period, accompanied by increases in body mass.

Clutch size and number of young fledged has been shown to increase with female age until approximately mid-life, when reproductive performance declines. We used a long-term dataset (2002–019) to investigate age-specific effects on reproductive parameters

China is a global hotspot for cuckoo‐host diversity, with 17 cuckoo species, exploiting 142 host species. We reveal adaptive matching in body size and egg traits, along with niche partitioning among cuckoos, while identifying eight new host species.

Non-passerine birds from Laguna Melincué Ramsar Site, Santa Fe province, Argentina [PDF]
We present a waterbird inventory of the Laguna Melincué Ramsar Site in southern Santa Fe province, Argentina. We record 109 species from 28 families of non-passerine birds, including the 14 Nearctic species, four southern austral migrant species, three ...

Geographic range size and evolutionary age in birds [PDF]
Together with patterns of speciation and extinction, post-speciation transformations in the range sizes of individual species determine the form of contemporary species-range-size distributions.

Passerine morphology: external measurements of approximately one‐quarter of passerine bird species [PDF]
AbstractStudies of community organization and clade diversification that include functional traits have become an important component of the analysis of ecological and evolved systems. Such studies frequently are limited by availability of consistently collected data. Here, I present a data set including eight measurements of the external morphology of
