Variation in extra‐pair paternity (EPP) among individuals of the same population could result
from stochastic demography or from individual differences in mating strategies. Although the …

A central problem in evolutionary biology is to determine whether and how social
interactions contribute to natural selection. A key method for phenotypic data is social …

Organisms should aim to time their reproduction to match the optimal ecological conditions
and thus maximize their fitness. However, social cues have been identified as determinants …

Avian nest defence, which is expected to serve both antiparasite and antipredator functions,
may benefit or be detrimental to birds, although selective forces that potentially operate on …

Farmland bird species have suffered dramatic declines in recent decades, especially in
Mediterranean areas. The intensification of agricultural practices has led to reduced …

Because of its parasitic habits, reproduction costs of the common cuckoo (Cuculus canorus)
are mostly spent in pre-laying activities. Female costs are limited to searching host nests and …

Agricultural intensification is considered the major cause of decline in farmland bird
populations, especially in the Mediterranean region. Food shortage increased by the …

The sensitivity of population trends to the climate and environment is generally considered a
species‐specific trait. However, evidence that populations may show different responses to …

Understanding ecological interactions among protected species is crucial for correct
management to avoid conflicting outcomes of conservation planning. The occurrence of a …

Lesser Kestrel Falco naumanni (Fleischer, 1818) populations have been one of the best
monitored bird populations in Spain over the last 70 years. These populations suffered a …
