Nesting period

Waders have started to nest. Although this year the window of opportunity for breeding is much wider due to the extremely early spring and therefore less snow cover and higher temperatures, birds do not seem to have taken the great opportunity to starting early. Of all wader species of our study areas, only Ruffs (Philomachus pugnax) seem to have begun to incubate earlier than previous years. However, vegetation and arthropod activity (main food resource for waders) is quite advanced. So how will waders match the peak of arthropod this year with the chick rearing period?

We have already found nests of all most common wader species in our study areas. Only nests of Wood Sandpiper (Tringa glareola), Common Snipe (Gallinago gallinago), Bar-tailed Godwit (Limosa lapponica) and Whimbrel (Whimbrel) are still missing in our list. Even two nests of Broad-billed sandpiper (Limicola falcinellus), one nest of the Eurasian dotterel (Eudromias morinellus) and an unusual case of a Golden Plover nest of five eggs have been found!
