La membrana nictitante o tercer párpado es una lámina transparente que se deliza transversalmente por el ojo en aves, reptiles y anfibios principalmente. Su principal función es proteger y evitar la desecación del ojo.☝️☝️

The satin bowerbird (Ptilonorhynchus violaceus) is one of the most romantic birds in Australia. He decorates his nest area by collecting as many blue items as he can find and scattering his goodies around to try and impress the ladies. This nest is in one of the sites we’re working at near lamington national park. His items include nerf bullets, felt tip pens, clothing pegs and drink bottles Lid. I’m not too sure how he found so much blue in the middle of nowhere but I hope the ladies love it. 🐦💕🐤
I threw In a pic from google so you could see the man in action shooting his shot. .
