Has anyone heard anything about the egg yet ? is there an embryo in the egg? I know anything else may take awhile.

David had several requests for the egg to be removed from the nest so he knows that we're all anxiously waiting for word on the condition of it. I'm sure he'll post information as soon as he receives it. We just have to be patient Smile.

No eagles present, it's calm and cloudy, looks like it's raining a little, can see water droplets.

Yes, we talked to David at the presentation last evening. I didn't jump on here and comment on what he said because I didn't want to steal his thunder, so hopefully he has had time to put something up on the website to do with this.

What David said to me was that the egg was taken to a lab for analysis and was found to be infertile, so it never would have produced anything. This may be an ongoing problem for this pair, and it does seem so sad that they go through the motions every year and work so hard to have babies.

Does anyone remember this couple ever having viable eggs that hatched?

2009 was the first year of breeding for this young eagle pair. Both eggs failed that year, the nest blew down in 2010 and again this year the eggs failed. Sad Sadly they have not had any success.

I look forward to reading David's report on the egg failure for 2011.

It will be very sad and heartbreaking if this is their fate. I hope David can elaborate on this more and if it's just inexperience on their part or that they will never have fertile eggs. It will truly be very sad.

eagles are monogamous; a pair will mate for life if all is well. A partnership may be broken if one of the birds is infertile, and a widow or widower will take a new partner.

Some reasons for infertile eggs


Reproductive failure is a problem for bald eagles and ospreys. Much of the problem stems from man's use of now-banned toxic chemicals. DDT, dieldrin, and other chlorinated hydrocarbons sprayed to kill insects, drain into rivers and get into fish. Eagles and ospreys eat a lot of fish, and accumulate the chemicals in their bodies. Other pollutants such as PCBs and heavy metals may also affect their reproduction.
infertile eagle eggs have been found to have a higher mercury content .


;Inadequate dietary calcium, sodium and energy can interfere directly with egg laying and fertility.

Over-supplementation of zinc can cause infertility.

;Age and experience of birds

;
