Two of the species we have trapped are the Rufous Fantail and the Tinian Monarch. The thing is, they both like flies. It’s very important to give the birds a diet as close to what they ate in the wild as possible. So where do you get the flies? Well, you start with tuna.

fly trap 2Here’s how it goes: you take a large metal tray about 4 inches deep and put two whole tuna in it. You take a 10 gallon bucket and cut the bottom off, turning it into a tube. Then set it over the tray. You take some window screen and make a large cone out of it, as big across as the 10 gallon bucket, then cut a small hole in in the point. You now have a fly funnel. Tape the funnel to the top of another bucket and push it inward so that it points to the bottom. Then put the bucket with the funnel upside down on top of the “tube bucket” that’s over the tuna. Wait. Flies will gather, and fly up into the tube and onto the screen and get trapped in the bucket.

Pull the funnel so that it is now pointing at the sky, and put the hole in the petri dish over the hole in the funnel and wait. Soon the dish will be full of flies. Place the dish in the cage, pull off the lid and quickly shut the door. Voila, that’s all it takes!!

That and a strong stomach for the smell!
