Sadly there is a 50% mortality rate with these guys...
I've got a blue jay story of my own to share. There was a wild flock of Blue Jays I used to tend when I was in California. I put food out for them (and they would actually fly to my window and tap on the glass to get my attention when the feeder was empty, then fly to a branch above the feeder until I filled it.)
One year, there were three new hatchlings that the parent bird brought around. Two were healthy, one was a runt... (and his siblings used to beat him up and steal his peanuts!) Poor thing wasn't getting any food. So I began putting his peanuts INSIDE the house, and giving him extra.
The first time he went to go get one, DAD quite literally flew off the fence and tackled him in my yard to prevent him from going inside. But he was so hungry, he "disobeyed" dad and came inside anyway... His reward was an open door, and all you can eat food dish.
Soon, the runt wasn't a runt anymore. And when his siblings figured out that he was getting extra food by coming in the house, THEY ALSO began coming in. But THE RUNT was always my favorite wild bird...
One day, I took a nap on the couch with no less than 8 parrots on either my person, or the back of the couch. It was a hot day, and the sliding door was open... I woke up with 11. The three birds came in, and saw it was "flock nap time." When I woke up, they were immediately out the back door... BUT clearly, they had been accepted into the flock.
THE RUNT used to tag along with us when I took my birds out for our evening walks. He would fly alongside from tree to tree chirping at us. "Wait for me, I'm coming too."
THEN HAWK NESTING SEASON STARTED. Suddenly the only bird who came around was Mom, Dad and "the runt." Until one day, I was watering my yard, with my front door open. I heard the runt screaming in a panic, flying full speed ahead, towards my open front door. Only a few yards away from me, a red tailed hawk dove down and plucked him right out of the sky... he made it to about the sidewalk. He was the length of my yard from safety.
But he was dinner. PURINA HAWK CHOW. I saw it happen, so at least I knew what happened to him, and didn't need to wonder why he didn't come around anymore.
IN ALL THE YEARS I FED MY SCRUB JAYS, ONLY MOM AND DAD SURVIVED. AND FOR SOME REASON THEY SURVIVED YEAR AFTER YEAR. None of the babies lived much more than a year. They always ended up being someone's dinner. THAT, UNFORTUNATELY, IS THEIR ROLE IN NATURE.
I miss my little runt, but he would have been left to starve, and wouldn't even have lived as long as he did had I not fed him. And the trade off was, he made a run for it, when maybe he might have lived if he had hidden instead. (OR maybe the hawk would have found him anyway.)
You tried. That matters.
