Earlier this morning our osprey pair had one and a half hours of peaceful bliss on the nest before the intruder osprey appeared and drove off the female, Bella. The male, Benecio, had left the nest about twenty minutes earlier.

During the pairs stay on the nest they were able to mate. If this couple can establish control of the platform, they will have a great deal of work ahead of them to prepare it for their eggs. As much time and effort these ospreys have invested into this nest over the last two seasons I'm sure they do not want to lose it.

How long will Bella and Benetio wait for the intruder to leave before going elsewhere? I am thinking time is of the essence now.

Good morning Carol,

I'm not quite sure. I did see Bella on the nest this morning for about 15 minutes before she flew off. She was on the nest when I got to work.

I haven't seen the intruder as often, but it did appear as soon as Benecio arrived with a fish.

Hopefully it won't come to pass that our couple finds another home.

If the mating yesterday was sucessful, when are eggs expected to be laid? I'll be willing to bet when Bella lays an egg, Benetio will drive the intruder off.

If the couple's mating was successful we could potentially see eggs after March 18. Last season it was within 5 weeks of mating to laying eggs. Osprey gestation is generally between 38 and 40 days. Last year's clutch was 37 days, 38 days and 37/38 days.

Our couple Bella and Benecio have a lot of work to prepare their nest. I did see Benecio bring in some spanish moss yesterday, but it was quickly removed by the intruder osprey. We're hoping the intruder does not prevent our couple from establishing this nest and moving into another area.

I'm beginning to wonder if we will have ANY nesters this year. I would think it's almost too late to prepare an adequate nest. Am I off base here? Wouldn't Bella and Benecio be fighting for their spot if they intended to use it again?

Benecio was on the nest earlier this morning and brought in a few sticks. I haven't seen much action since then, but I haven't been able to monitor the nest activity as much today.

When Bella and Benecio first arrived two seasons ago, they didn't begin their nest building until March 5, 2008, so we're not giving up on them yet. It has been disappointing thus far, but we are hoping the intruder leaves soon and this couple can settle into nest construction and parenting.

I did notice yesterday that both Bella and Benecio were driving the intruder away from the nest. I've yet to identify the sex of the intruder, but I believe it to be female. Usually the intruder appears when Benecio brings a fish to the nest.

Keep your fingers crossed that the intruder finds another home and leaves B&B alone.

OK, all fingers are crossed. Knowing that two years ago the nest building started in March gives me hope that we will be successful this year. It looks like there are more sticks & stuff there today, but that hole is still looming large.

The intruder sure sounds like a home wrecker! :( But thanks for your encouragement. This will be my first year watching right from the start!!!

Our friends are busy on the nest this morning. One of them just brought a large stick and put it on the side where the hole is. In the few minutes I have watched he/she has made three trips out of and into the nest with sticks. It looks like the birds are working with and not against each other. I hope our "bad girl" has flown the coop!
