Is it Normal for Peregrines not to have eggs yet?

Just wondering if anyone out there knew. These two falcons keep me guessing on a daily basis. Today the male was on his favorite perch and the female flew out of the nesting box and up on top of the 446 Main Street building. By the time I made it to the top floor of the building, either she or he were back at the next box.

I thought that Peregrines would always make sure there was a falcon on the nest at all times. I am hoping someone out there with knowledge of Peragrines can answer this for me.

Thanks!

I think a lot depends on the location (esp latitude) of the nest. The link Deborah gave was for nest in Pittsburgh where the previous earliest egg was March 23. I'm keeping an eye on the falcons in Rochester New York (http://rfalconcam.com) and the first egg in 2007 was on March 26 and last year it was March 27. I'm jealous you have Peregrines you can watch - I've just got me cams. ;) --- Oops, sorry for deleted comment. I just wanted to add - there's no eggs in Rochester yet this year, but there have been some other issues with them - usual male did not return & nest boxes were moved - so it's not surprised they would be 'behind'.

Hi Kallen - looking at your photos from an earlier post I would say there are no eggs yet. The female will sit tight when incubation starts and the male will take over duties when she needs to go for a 'wash and brush up'. Our Peregrine's are probably at the same stage as yours. Keep watching though. Once they are incubating it will be about 34 days before the eggs hatch and about 40-45 days after that they should fledge.

great-I don't need to find the answer-I can just look at your reader's comments.

According to the latest breeding bird atlas, Peregrines in New York state lay eggs anywhere from March 2 to June 19, and the dates in Massachusetts should be similar, if perhaps average a bit later for the early date. So nothing to worry about yet.

Thanks all. I will check it out this weekend!! I am heading to bed due to allergies.

She has definately not laid her eggs yet but she is sticking close to that nest box of hers! The male doesn't seem that interested in her either. He spent the day snoozing on the ledge. I have never seen a bird sleep before so it was so cute to see!! I love these birds!
