If you have looked closely at the box when the adults are not there, you will have seen the new egg, the second of the season.
If this is your first year looking at a peregrine nest, you may not know that their eggs are a gorgeous, richly colored reddish-brown. They are one of the most beautiful of all bird eggs and were highly sought after by egg collectors in the late 1800's and early 1900's.
The normal sized "clutch" for peregrines is four eggs. There are often fewer and very rarely more. We have seen five eggs only once in Washington at the Tacoma site several years ago.
However, two years ago, we observed 8 eggs in the WAMU nestbox, a record for peregrines. We suspect that two different females each laid a separate clutch in the box, most likely after the first falcon had died. Unfortunately we can only speculate about this incident as we had no camera at the time.
