Here are some snippits from the blog on the website. There is more information on the blog (between my ...'s) where the layout of the nestbox, camera's and ledge are explained in more detail.
Everything continues to go very well with the chick. It is growing fast! It is also advancing in its development such that it is becoming more mobile, preening, and vocalizing. It is mobile to the extent now, that it has strayed out of camera view a few times, causing mild panic in more than a couple of viewers....Even though the chick will wander, it will consider the nestbox its "home base" and return there if it feels threatened, to be fed (at least for now) and to sleep at night.....Bottom line, please remember there will be times when the chick is NOT visible. Two cameras on the ledge are nice but they do not offer 100% view of all nooks and crannies of the box and ledge.
