First black-tailed godwit egg of spring found

This video from Sweden is called Black-tailed Godwit (Limosa limosa) islandica; juvenile birds.

Translated from Landschap Noord-Holland in the Netherlands:

The first black-tailed godwit egg of the Netherlands was found on Wednesday, March 25th, 2015 in Uitdam, Noord-Holland province. The nest was found by wader protector Ab Kalkman from Amsterdam, on the land of farmer Anton Dirksen. This couple found also in 2011 at exactly the same place and on the same date the first godwit egg of the Netherlands. Experts assume that it is the same godwit.

Rare breeding birds in the Netherlands

They included one shag nest, which unfortunately failed.

Dutch reed warblers depend on African rainfall

This video is about a young cuckoo, fed by its foster parent, an Eurasian reed warbler.

Translated from the Dutch SOVON ornithologists:

When it rains in the Sahel more Eurasian reed warblers survive

Friday, March 20th, 2015

About various migratory birds including the purple heron and the sedge warbler it was already known: if there is enough rainfall in the autumn in their wintering grounds in West Africa, it increases the likelihood that they will survive the winter.

An analysis of reed warblers captured in the Netherlands shows the same effect. How many reed warblers return to the Netherlands therefore depends in part on the amount of precipitation that falls in West Africa. This is reflected in the Breeding Birds Report 2013 published today by SOVON.
