Today is the first day that either Bea or Jasper has not incubated the overdue eggs. The pair continued incubation for over a month after the hatching timeframe. The chicks should have hatched the first full week of April. We believe that the eggs weren't fertile.
The pair should remain on the platform to retain ownership of the site throughout the summer.

Unfortunately for the pair, Bea and Jasper, they will not have any chicks to raise this summer. The chicks should have hatched the first full week of April. Today marks the 59th day since the 3rd egg was laid and the 54th day for the 4th egg. This is a first for the pair to not have any chicks hatch. The last two years the chicks and eggs fell through the nest leaving the pair with no offspring. As you may recall the first and second egg were from a different male.
So why didn't the eggs hatch? Osprey eggs fail due to it either being infertile or nonviable. Infertile eggs occur when the ovum (egg) is not fertilized before it begins its journey down the female's oviduct. Ospreys copulate frequently before and during egg laying, which helps assure that sperm is present at the right time (when the ovum arrives). Incomplete, poorly timed, or insufficient copulations can result in unfertilized eggs.
A nonviable egg occurs when an embryo fails to develop properly and dies. This can happen for many reasons:

A nonviable egg occurs when an embryo fails to develop properly and dies. This can happen for many reasons:
- Insufficient incubation. Eggs must be kept at a proper temperature and turned often. Temperature is vital for development to begin. Eggs must be exposed to temperatures between 99 and 104 degrees°F. Turning eggs prevents the developing embryo from sticking to the side of the egg and provides fresh nutrients for proper development.
- A cracked shell. If the egg shell is pierced or cracked before the embryo is fully developed, it will die. This can be from the egg being stepped on or jostled to vigorously.
- Bacteria or chemical contamination. Contaminants can make their way into an egg and impede or kill the embyro.

Today marks the second week since the third egg was laid and eleven days for the fifth egg. We don't anticipate the third egg being viable as it was not incubated for several days. The third egg is the mostly brown one.
We believe we could see some chicks after April 11th, which begins the 35th day since the first egg being laid. We haven't had any osprey chicks the last two years so we are anxiously awaiting the month of April.

We have another osprey that is attempting to land on the platform. Currently Jasper is away from the nest leaving Bea to fight off the intruder. Upon writing this Jasper has returned.
The intruder osprey has been flying about the nest for about an hour now causing the pair a bit of stress. Bea is back to incubating the eggs.

Bea has laid her fourth egg, the second for the pair, Saturday, February 24th. the 3rd egg was laid February 21st. Initially Bea laid two eggs from a previous male, but those eggs were not incubated. The two cinnamon colored eggs are from Jasper. The brown egg is from the first male and not viable.
Below is Jasper from this morning with the eggs.

Bea has laid another egg. It is possible this egg could be produced from Jasper. The dark cinnamon colored egg is the latest egg. Bea or Jasper could push the older egg away from the nest cup since it is no longer viable.
Bea seldom incubated her first two eggs, but has immediately incubated this egg and continues to do so.
