Folks.

I've read in both the book "Into the Nest (by Laura Erickson & Marie Read) and on the Lab's Birds of North America online that, on the average, male goldfinch live longer than females. Can anyone shed light on why this is so? I recently purchased a new niger tube feeder that is 3 feet long with a spiral wrap-around perch. It can handle many finches and is not disappointing!So far I've had a total of 8 finches there at the same time. But I AM seeing many more males than females and hence my question. Thanks for the help!!
