You never know what kind of behavior you’ll see from a bird blind. If the blind is good (and the birders are quiet), the birds should be comfortable and you’ll get to see them acting naturally. From the Grauwe Gans hide in the Oosvaardersplassen area, I spent some time watching a pair of Eurasian Spoonbill allopreening. Allopreening is mutual grooming, usually associated with pair bonding. Spoonbills have such long, unhandy-for-self-preening bills, I’m not sure this is pair-bond behavior or simply a mutually beneficial preening co-op between friends. Notice the surrounding geese are also taking the time to beautify themselves. Click on any picture to embiggen.
