Data from: Climate change and bird reproduction: warmer springs benefit breeding success in boreal forest grouse
Global warming is predicted to adversely affect reproduction of birds, especially in northern latitudes. A recent study in Finland inferred that declining populations of black grouse Tetrao tetrix could be attributed to advancement of the time of mating and chicks hatching too early – a support of t...

Breeding season temperatures increased, being most pronounced in April. Although the onset of spring advanced nearly 3 weeks, peak of mating advanced only 4-5 days.

Both brood frequency and brood size increased during the study period, but significantly so only for brood frequency in capercaillie. Whereas the frequency of capercaillie broods was positively affected by rising temperatures, especially during the pre-hatching period, this was not the case in black grouse. Brood size, on the other hand, increased with increasing post-hatching temperatures in both species. Contrary to the prediction that global warming will adversely affect reproduction in boreal forest grouse, our study shows that breeding success was enhanced in warmer springs.
