Cariber Flamingos are a variety of African birds that I saw in Copenhagen zoo. With their red+ orange colour they are very attractive. The are always busy cleaning themselves with their beacon, standing on one leg, so it is very difficult to capture their clear neck.
See their group picture below- every single bird is busy cleaning itself, has no time to keep its neck up for a moment!
