Synchronisation of parental behaviours reduces the risk of nest predation in a socially monogamous passerine bird.
Konrad Leniowski,Ewa Węgrzyn +1 more
TL;DR: It is demonstrated that synchronisation of parent feeding trips significantly decreased parental activity at the nest, and nest survival time increased with the synchrony of parental feeding trips.
Resource allocation between growth and endothermy allows rapid nestling development at low feeding rates in a species under high nest predation
TL;DR: A strong negative correlation between feeding rate and growth rate demonstrates that blackcap nestlings develop their bodies under relatively low feeding rates and more feeding is needed for maintenance of body temperature than for body growth.

Is UV and blue-green egg colouration a signal in cavity-nesting birds?
TL;DR: The study indicates that it is blue-green, not the UV component of the egg's spectral characteristics, which seems to increase the perception of eggs by adults in dark cavities, which might have been the most important pressure towards evolution of blue- green colouration of eggs in cavity-nesting birds.

Do all aphids benefit from climate warming? An effect of temperature increase on a native species of temperate climatic zone Cinara juniperi
TL;DR: The study demonstrated that environmental conditions significantly affected phenology of juniper aphid, and suggested that the increase in temperature recorded in recent years went beyond the temperature optimum of the study species.

Nest Site Preference and Nest Success in Blackcaps Sylvia atricapilla in Poland
Ewa Węgrzyn,Konrad Leniowski +1 more
TL;DR: The effect of nest site location: in bramble, elder or hornbeam, on breeding success as well as selection of different nest sites in the blackcap Sylvia atricapilla, a species whose nests are heavily preyed upon both by rodents and corvid.
