Abstract Purpose of Review We aimed to summarize the evidence linking multi-purpose
forest management (MPF) to bird nesting and fledging success in temperate and boreal …

Double brooding may be a good strategy for short‐lived species to maximize annual and
lifetime reproductive success (ARS and LRS, respectively). Nevertheless, there is typically …

Migrating birds have to incorporate migration into their annual cycle, next to breeding and
moult. This presents the challenge to arrive at the right place at the right time at any given …

Although the costs of reproduction are predicted to vary with the quality of the breeding
habitat thereby affecting population dynamics and life‐history trade‐offs, empirical evidence …

Nest re‐use in birds has the potential cost of infection by parasites and pathogens but may
also be a source of beneficial symbiotic bacteria transmitted horizontally. Eurasian hoopoes …

Tracking devices are used in a broad range of species for a broad range of questions, but
their potential effects on study species are debated. Outcomes of earlier studies on effects …

The difficulties in understanding the underlying reasons of a population decline lie in the
typical short duration of field studies, the often too small size already reached by a declining …

Avian eggshell colouration might function as a post‐mating sexually selected signal of
female quality, influencing male parental investment and, hence, reproductive success. This …

Growth is a fundamental life history trait in all organisms and is closely related to individual
fitness. In altricial birds, growth of many traits is restricted to the short period between …

Theory predicts that, even within the same population, birds may vary their breeding
investment with age. This may be due to an improvement in individual quality of old birds in …
