Drones back in 1908
German pharmacist Julius Neubronner trained pigeons to fly prescriptions and medications to and from the hospital. In 1908 he developed a lightweight miniature camera with a system in which air pressure controlled the time delay before the photograph was taken. Neubronner made several cameras, this is a panoramic camera with 3 x 8 cm flat film. The invention was used during World War I.

From across the pond I saw all four young Green Herons flying along this yellow boom. But by the time I got to the other side of the pond I could only find three of them. Aren't they adorable? The fun of watching them is only just beginning.

Edited alt text in first photo replacing the word "along" with "alone."

A young Green Heron is standing on a yellow boom and is facing the camera but looking towards the left. The heron's bill is orange but the tip is black. The heron's head, back and wings are a dark green while its breast is white striped burgundy and its belly is white. The heron's legs are greenish yellow and the feed have 3 splayed toes.

Two young Green Herons are standing very close together on a yellow plastic boom that is supposed to help prevent water chestnut from overtaking the pond. (It isn't working!) The herons are looking to the left. Because of the way they're standing, the heron closest to the camera is looking over its right wing. Unlike their siblings who like to spend time alone, these two youngsters are always together.
