On the Manitoba Forum, I stated the situation regarding our chick here at the U of A, and here is what Tracy, the peregrine falcon expert at the Radisson site, had to say:
Quote:
I would be very surprised if your chick wasn't being fed - you have an experienced mother who has had disturbances before and even the number of visits this year and cleaning out the nestbox shouldn't be enough to make her abandon her chick. Before cameras, we used to visit the nestboxes alot more over the nesting season (only way to see what was happening) and I've never had a bird even come close to abandonning their eggs or chicks.
Your chicks are banded so they won't get fed as often as they used to and with fewer mouths to feed, there won't be need for as many visits (some parents catch on to fewer mouths faster than others) and at this stage the adults feed the chicks less and the chicks feed themselves more, so whole bunch of changes in eating behaviours now which means viewers may need to change their viewing behaviours as well.
My suggestion would be that anyone up and willing to watch should keep an eye on the box between 0300h and 0600h - that is when meals started arriving at our nestboxs and there were usually a couple between these times. Even when the chicks were younger, room service would be often early morning and almost nil through the day and a couple between 1600h and sunset. Ivy right up until all the chicks had left the box used to turn up with food between 0300h and 0400h with food. Even if you can only see outlines, you should be able to see food in the feet as the birds come in.
