The Oostvaardersplassen is always rewarding for bird photography; 2 specialists of this important wetland:
The colored Bearded Tit (Panurus biarmicus/Baardmannetje). In winter they feed on reed seeds. What an acrobatic posers are they.
The Bittern (Botaurus stellaris/Roerdomp) is seldom seen, as it leads a retiring life under cover of extensive reedbeds. Its presence is usually only revealed by a conspicuous call, resembling a foghorn. When ditches and lakes are frozen, hunger drives them to the few scarce places with open water. The first photo freezes a catch action. On the second photo the Bittern adopts the characteristic camouflage posture. Note that especially the dark breast markings work well.
I spent about an hour with it and shot over 4Gb of images … and then drove home with a very smugg grin on my face!
