Watching & Waiting
Those who liked to peek in on the falcons at night were long able to take advantage of the buildings lighting to keep an eye on the birds. A problem with the lighting has darkened the ledge at night. We can see a flickering bulb on camera, but at this critical stage we are unable to do any maintenance on the ledge.
We have a further difficulty in the early morning when strong light from the rising sun illuminates every smudge and scratch in the camera dome, confusing the autofocus feature of the camera which confuses this glare with a close object. A camera operator is not always available to correct this issue but we are trying to ensure that we refocus the camera as quickly as possible.
We are drawing close to hatching for our eggs! Falcon incubation averages about 33 days. Calculating the date of the first hatching can be tricky however as the birds don't really start to incubate in earnest until the second egg is laid (even later if the weather is quite warm). The purpose of this is to minimize the size difference between siblings, preventing the youngest from being at too great a competitive disadvantage.
The falcon egg prognosticator calculates that the 1st egg will hatch on April 21st or 22nd, this is approximately 35 days from the date the egg was laid.
