Birds have always been a challenge to study closely because they are so fast and can just fly away when you approach them.

This is what inspired Lisa, aka Ostdrossel, to put a camera in her feeder, which captured some really incredible photos of a variety of species of birds.

What’s special is that the birds have no idea they are being filmed, so they let their personalities out.

From a couple of birds having a shouting match to two doves ‘kissing,’ the camera captures a wide range of fascinating shots.

Most of the birds are just there to have a snack, one of our favorites is a crow who has a mouthful of kernels making it looks like a toothy smile.

Lisa shares on Tumblr how her setup works, “it consists of this camera box, much like a trail camera, that has a macro lens on the top and a regular one on the bottom.”

So inside the box, there is a shelf where the camera is placed, this camera has a motion sensor which can take 10 pictures each second.

Once a bird lands on the box, the motion sensor triggers and the camera starts taking pictures. The camera can take up to 7,000 photos in a day!

“My evening pleasure and routine is to go through all of them, delete the bad ones and keep and slightly edit the ones I deem publishable.”
