Falcons continue to visit! and bad news.

Hi All,
Bad news first: The Bird Banding Lab sent a note that one of the male falcon chicks banded on May 18th was found dead on June 3rd. Notably this coincides with comments by community members that a max of only three chicks were seen for a few days around that period. I will send any details when or if I get them. It is not uncommon. Birds do die and for falcons this post-fledging period of time is particularly difficult to survive through. I have read that survival estimates for falcon chicks through flegding to dispersal are typically very low, 15 to 40 percent.

Better news: Well, the falcons have been visiting the nest tray and have showed signs of pair bonding. While I am not sure exactly what this means it can only be good news for the pair and it is great for those of us who enjoy seeing falcons.

Many thanks for all the posts. FYI, I have responded to some questions regarign previous posts internally at those posts.

Until Next time,

Falcons flying!


Hi All,
Well, as many of you may be aware the falcon chicks have taken the leap! Following about a week or so of increased activity and wing flapping the falcons have flown for the first time. They will still maintain a presence at the site as they practice flying--indeed the adults will continue to care for them bringing them food for them to eat in the nest or near to it. These chicks still have along way to go. This is a difficult time for chicks, the probability of surviving these next few months is not high (probably < 40%). They have to become strong fliers and hunters and begin to fend for themselves. Let's keep an eye on them and wish them luck.
Until next time,
