Some species of birds mate for life, this list usually includes large birds with strong territory defending skills from lesser beings (not including human beings and their territory decimation of course) and large nests, so e.g., the bald eagles, black vultures make the list along with others like albatrosses and atlantic puffins, the scarlet macaws too. Most birds are monogamous for one breeding season, but do not choose the same mate in every season.
Personally, as long as they are respectful of the females choice and fight only other males, its all good to me and more importantly in this sentence I am talking about humans, animals and birds cannot be judged out of evolutionary context. So, when I saw a pair of plum-headed parakeets mating in Sattal, Uttarakhand and then saw the male feed (“KISS”) the female AFTER mating, I truly felt my world view shift. The post mating kiss, looked like a sign of respect (more than love, cos who knows what will happen next year!) and I always believe that without respect, love has no meaning anyway. So a joyous, respectful mating to all the beautiful birds out there, here I have two types of parakeets: plum-headed and rose-ringed, both shot in India and a pair of greater prairie chicken that are a breeding pair brought together by science and genetics, right here in Bartlesville, Oklahoma.
It is too early for the chicken to breed, so this painting is composed of two separate photos, not from real life. Hope to see the male courting dance next spring in their breeding facility.
