I did this for my loving boyfriend who misses his family that he’s been away from for the past 6 months.

That’s all I care about. He is missing his little brother grow up. The least I can do is something like this for him, for the sacrifice he is making.

Adorable
Japanese researchers at the University of Tokyo recently observed eight mating pairs of Japanese tits, a small bird species.
+
Professor Toshitaka Suzuki noticed they would flutter their wings to signal their mate to enter the nest first when returning with food. The researchers analyzed over 320 visits and found that wing fluttering prompted the mate to enter first about 90% of the time.
+
The findings, published in Current Biology, are notable because symbolic gestures were thought to be limited to humans and apes. This wing fluttering fulfills the criteria for a symbolic "after you" gesture as it occurs only in the mate's presence and encourages the mate to enter the nest first.

"There is a hypothesis that walking on two legs allowed humans to maintain an upright posture, freeing up their hands for greater mobility, contributing to the evolution of gestures. Similarly, when birds perch on branches, their wings become free, which we think may facilitate the development of gestural communication," Suzuki concluded.
