Gruttomania

The end of March and the first week of April is the best time to observe the complex and interesting pre-breeding behavior of Black-tailed Godwit (Limosa limosa/Grutto). This takes place in the afternoon preferably in flooded grasslands. The display of the brick-red ♂♂ - downward spreading of tail and puff out of the rufous mantle feathers - is needed to trigger the process of ♀’s ovule ripping. Other ♂♂ are scared off, by showing the white conspicuous underwings. Although the ♂♂ are very much present, the duller ♀♀ determine when the mating start. This is one of the many things that I learned over the years from Astrid Kant, the godwit specialist in The Netherlands. Thanks Astrid!
The photos below are taken in overcast weather conditions, I begin to appreciate such lighting conditions more and more.
