aha! at last Vents is making himself useful.
thanks Liz for the observations!
i'm reading a book by Helena Telkänranta which is called Millaista on olla eläin? the name could be translated as What it's like to be an animal?. she begins with describing different senses of animals (others than human beings) and compares them with the senses of humans. for example the senses of smell and taste of some birds are now known to be even better than those of humans.
Telkänranta writes that the sensations of touch of birds is nowadays known to be about similar to the sensations of humans. birds have sense of touch in their skins like we humans have. the sense of touch is most acute in their beaks and legs, parts which might at first sight seem improbable because they are covered with keratin. however, they are the body parts of bird which are most in touch with the outer world and therefor evolutionary selection has favoured the development of sensitivity in these body parts. the most sensitive body part of at least some birds is known to be the tip of the beak. here Telkänranta refers to a book by Tim Birkhead: Bird sense. What It's Like to Be a Bird (2012, London UK, Bloomsbury, p. 78; http://bird-sense.com/tag/tim-birkhead/). when for example a jackdaw or a budgerigar preens its partner's neck feathers it will feel a stronger sensation in its beak than the partner feels in its neck. this sensation may feel about the same as what we feel when we touch with our lips the skin of our partner. lips are one of the most sensitive human body parts.
this made me think that we haven't been wrong at all when we have called the feather pulling and and beak touching of eagle couples "eagle kisses".
btw, i learned in Birkhead's homepages that the preening of the bird partner is called allopreening (: http://bird-sense.com/chapters/ ; scroll down to Chapter 3. Touch). there are also two video clips of birds doing this.
btw 2nd time: Birkhead writes that a bird called a buffalo weaver experiences orgasms, uniquely for birds. i don't know how many bird species have been studied to see whether or not this is happening. i guess it would not be one of the easiest things to find out. i think i once saw Linda having an orgasm. she and Sulev mated on the nest and once she had her tail on the side of the camera. i think i saw something looking like an orgasm once when Sulev flew away from her back. i'll see if i can find this clip...
..... yes, i found it. it happened on March 12 2013. i made a new clip of the video to see if the picture quality would be better now 3 and half years later. - no, it's worse. the original is better i think, see the link below.

9:12 an eagle arrived. It was sitting on a branch, then jumped to the nest, and then returned to the branch. It has rings, but I cannot see them properly in this light.
9:23 the eagle left.
that was Shilute on the branch. Vents came and she jumped down to the nest. after a short while she went back to the branch. after a few minutes she flew out and in a while Vents followed her.
10:42 now one of them is back. i could not see which... Shilute?
--- no it was Vents.
10:45 Shilute arrived.
there was some eagle kissing.
