They're pretty much normal-sized feeders--the kinds you would see in any shop seeling feeders. I guess they hold about a pint and a half--or maybe a little less. Tonight just before 7:00 my dad looked at the feeders and said, "I need to fill them again." I asked him why so since night was falling, and he said, "Oh, they'll drink it all up." I counted nine hummingbirds working on one feeder today--just batting each other around trying to nab quick drinks.

A week ago I decided to strap a surveillance camera to a tree close to a bird feeder to see if birds feed at night. The camera is equipped with a flash and the motion detector snaps the shot. I activated the camera at the break of dark. The first night the camera recorded eighteen hits, so, inspired by this thread, the next night I positioned the camera to record the events around the hummingbird feeder to finish out the roll. Success! By dawn all the pictures were taken. Yesterday the photos were returned from the developer and were a bit of a disappointment but interesting. The bird feeder pictures were of two cardinals (a bright red male and a beautiful white and pink female who contrasted well with the backdrop of black.) and three pictures of the bird feeder but no bird. The hummingbird feeder night did worse. The camera recorded eight pictures of the hummingbird feeder but no bird. Hmmm, maybe the hummingbird feeder swings in the breeze. Maybe the hummingbirds are too fast for my camera. I'll try again this week.

How does the surveillance camera work? Does it shoot single shots every few minutes--or what?

amememba pointed out he used: ...camera is equipped with a flash and the motion detector snaps the shot. I activated the camera at the break of dark.
other camera's just take a 'snapshot' every 10 to 15 seconds, others still work on other methods, --some are sound rather motion activated.
motion detectors have gotten really cheap --they are commonly used on exterior lights (i used to have them on my front door) and in ladies rooms and store rooms, the lights come on when the door is opened, and go off X miniutes after they stop detecting motion.
but they are hard to calibrate. my exterior door lights detected motion in the street as well as on the sidewalk.. so passing cars could activate the lights. --fortunately, my house was on a dead end street. i am seriously thinking of getting a motion activation switch for my entry hall in the apartment.. i like coming into a lit house/room, i hate leaving a light burning all day!

Right, of troy. I had the motion detector set with a fifteen second delay between pictures. This, though, might be too long for birds. (the idea was to save film for visits by other birds). This week I'll try to get a digital camera rigged up. If this works I'll post my results on this thread.

Oh, many thanks, et', for this link. Those photographs were fascinating and I shall print them out on high quality paper and will try to figure out some kind of writer's response to them for my kids at school to go through. Fabulous. What a treasure trove! And why did one little bird fall out of the nest? Many questions now. Again, many thanks for giving this to us.
