Glass buildings, concrete buildings, water..in this case they are under a bridge, major traffic above, predators, electrical wiring, bad storms... It's a hard world for them and it's experience that teaches them how to survive.
At our site it's the glass buildings that kill them. In central Ontario we've pretty much destroyed any habitat they used to nest in, all the cliffs are either gone or eroded so now they nest in the cities and there are many things here that are not part of their natural world.
The Maine chick died after he fledged, he was found on the side of the highway bridge I believe so I expect he was killed in traffic but that's just a guess. They are under a bridge and that bridge actually lifts up to allow ships to sail through - they close traffic on both sides and the bridge raises up in the middle and the ship goes through and then it goes back down to being a road again.
Kinderchick:
Very sad. :'( Why is it so difficult for falcon chicks to survive the post-fledging period, carly? ???

Maine falcon news: Posted by Mac over at BCAW
I do want to pass along some bad news. 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. This 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 fledging to dispersal are typically very low, 15 to 40 percent.
Alison:
I was concerned because I didn't see more than three juvies at any one time, even when a parent came in with food, but I did actually see all four for a few milliseconds. The fourth juvie was zipping around behind the box, and occasionally I could see the top of a fast-moving back for a moment.
Alison:
They are doing a lot of wandering around: looks like a little male in the box.
