There are various theories about why mockingbirds flash their wings -– to startle insects, ward off predators, attract a mate. Many birds are observed sunning even on the hottest days, however, and it is believed that sunning can fulfill purposes other than just temperature regulation. Yesterday I saw my favourite baby robin that feeds from my feeder laying on its stomach on the ground, with its wings spread... this is really near a window and I feared it had been stunned... but i'd been in the room and heard nothing, and when another bird went nearby it jumped up, absoultely fine! If you see a bird lying on the ground with its wings spread, you can be pretty sure it’s doing something called anting. Yesterday I saw my favourite baby robin that feeds from my feeder laying on its stomach on the ground, with its wings spread... this is really near a window and I feared it had been stunned... but i'd been in the room and heard nothing, and when another bird went nearby it jumped up, absoultely fine!Today, after what looked like playing under the feeder between two baby robins and one of the parents, the parent and one baby flattened themselves to the ground and spread out their wings.What are they doing? Most stand in the water, often thrusting down and forward with their head to force water up onto their back. Those who don't believe in magic will never find it.

So nice to see that the parents joined together in defending the baby – it’s a perilous time for the young ones. "I don't know about robins but my juvenile blackbirds have been doing the same thing.I think they are just resting or sunning themselves as they do it with their beaks open and wings spread out.Maybe the young get more overheated than adults?Agree with madpenguin! The birds invariably adopt a posture in which the body feathers are fluffed up and one or both wings are held out from the body, with feathers spread. Those who don't believe in magic will never find it. Different birds will sun in different ways, but common sunning postures include: This year I clearly saw the birds catching and consuming insects just after a completed wing flash.Later in the summer, I witnessed a similar kind of wing flashing used as a hunting technique by an entirely different species, the snowy egret (It is thought that the egrets use their large feet to stir up the sand underwater so that they can more easily see potential food as they forage. Sunning can help birds convert compounds in their preen oil, secreted from a gland at the base of the tail, into vitamin D, which is essential for good health. I can't remember all the detail about anting but the bird allows the ants into their feathers to help with parasite control I think. With strangers, cats or squirrels, WW3 begins. Scientists aren’t sure why birds do this.
I also wondered, after reading the post about playing-dead, whether it was a way of staying unnoticed by predators, sticking low, not moving, earth-coloured....You're right about the beaks being open, they certainly seem to pant, which suggests cooling? I observed three birds yesterday, one a robin on mulch, one a jay and another a robin on grass, crouched low and motionless for some time, wings spread and chests touching the ground. One of the things I love about wildlife watching -– you can always see and learn something new!Interesting theory and observation. I’m sure that the mockingbirds will flash their wings for other reasons, too.
Why would 3 different birds (blue jay and robins) be on ground crouched down with wings spread? If you see a bird lying on the ground with its wings spread, you can be pretty sure it’s doing something called anting. Watch a Blackbird doing this in your garden and you will soon see how the bird works each feather in turn, carefully ‘nibbling’ the feather. More routine maintenance happens on a daily basis and involves a combination of preening and bathing.Preening involves manipulating individual feathers with the bill, often realigning the filaments that hook together to hold the feather in shape. Hundreds of bird species engage in sunning, and some of the most common birds that birders may see sunning include doves, pigeons, vultures, cormorants, darters, anhingas, tits, titmice, jays, and sparrows . S/he flew to another tidal pool and then began running to and fro in the water, flapping his/her wings open and closed.Occasionally, this was complemented by a leap into the air and plunge into the water – obviously behavior calculated to startle and scare up the fish lurking below the water’s surface.It was fascinating for me to see two such different bird species using their wings in a similar fashion as a hunting method.
Since there aren’t insects to be had atop the fence, I suppose the wing flashing is reflexive.
House Sparrows, in particular, work the dust into their plumage by using flicking movements of the wings.Registered Charity Number 216652 (England & Wales), SC039193 (Scotland)© British Trust for Ornithology, BTO, The Nunnery, Thetford, Norfolk IP24 2PU, Tel: +44 (0)1842 750050 Fax: +44 (0)1842 750030
