First egg for Spirit and Roger! From the blog: I translated it from the French. Wednesday, April 3, 2013
The first egg of 2013
It is apparent that without the cameras inside the nest box, it is difficult to know exactly when egg laying took place, how many eggs there might be, etc. But by observing the comings and goings of the two falcons, one can still have a good idea of the important dates, like the laying of the first egg, hatching, etc.
Today, we saw the first sign that an egg has been laid in the nest box. In fact, until now, Roger had not been spending more than a few minutes at a time at the nest box, even when Spirit was not there. Since we had cameras inside the nest in previous years, we have seen that as soon as the first egg has been laid, Roger stays in the nest box to incubate it during the times when Spirit is out of the nest. So, this afternoon, there was Roger spending 30 minutes at the nest, and here is the video captured by the motion detector connected to the telescope in my office:http://www.youtube.com/watch?v=0-QSZBx2rVw#This is an indication which does not lie! It is likely that the first egg was laid in the morning between 7:20 a.m. and 12:40 p.m. Why not before 7:20? Because Roger went to the nest box around 7 a.m. after having delivered breakfast to Spirit, but he only stayed for a few minutes. Spirit returned to the nest at 7:20 after she had eaten and did not reappear until 12:40, in spite of visits by Roger, who probably wanted to mate, or simply to make sure that everything was going well inside . . .
Spirit and Roger have made us become accustomed to an early first egg in 2010 and 2011. On the contrary, in 2009, I had estimated the arrival of the first egg around the first of April. If this goes in the same way as in previous years, Spirit will lay three more eggs (one each 48-60 hours). We count 33 days of incubation from the time of arrival of the third egg, which gives us a hatch date around Mother's Day, if all goes well . . .
How will we know if there is a hatch? While the falcons sre in incubation mode, they never eat in the nest box. When the first chick emerges from its shell, we will see food brought into the nest box for the first time to fill the tiny, hungry beak! Let's cross our fingers that everything will go well from now on.
