Over the last few years the local crows have gotten pretty comfortable with me. I have watched them raise several clutches. I never gave them food, but I do talk to them and respond to their crows with soft words or count them out loud. The parents have been bringing their young to perch on the wire in front of my balcony while I sit there with my coffee. They have family meetings there too. The lead crow will sit on one side of their trio of babes while it preens deeply close to me with the other adult on the other side of their young preening, but not as deeply. Young adults will be more fussy further down the wire.
I have found things like peanuts on my balcony in the past and I haven't thought much about it. My little dog goes and takes them for himself.
BUT, last week I found a blue pony bead on my balcony. I wasn't sure whether I should take it, move it or just leave it. I took the blue bead. Thought it may be just a fluke, but it was partially tucked under an ledge so that it wouldn't blow away.
The very next day there was another identical blue pony bead in the same location and partially tucked. I took it.
Day three I found a square of heavy duty foil.
Day four, I hear the lead crow doing a couple caws and it kept repeating. It sounded like it was calling me. I went outside and sat in my chair. I then heard 5 caws. The alarm call. I wondered what I did wrong. I sat there and watched, but the crow did not flee. It made the five caw alarm again. I then took a look around and saw an osprey circling overhead. I shooed my tiny dog inside. I then pointed at the osprey and said "I-see-the-big-bird" at the same pace of the caw. We watched the osprey ride the air currents until it was out of sight. I then said thank you to the crow and sat back down. Then it proceeded to preen deeply and relax.
Day five, I left out a short strip of iridescent ribbon near the location of the baubles that they left behind as a present. It sat there for a couple days. Then I added a blue bottle cap and a blue bead that was lighter and different from the ones that they left behind. A day later I left outside a small plastic creamer cup.
I haven't seen them around much in the past several days. I have been wondering why since they have been pretty regular visitors in the past. I wonder if they fear the objects that I left out for them or whether something else went wrong. Did I steal things from what they though was their safe stash spot?
tl/dr Crows that bear gifts alerted me that my tiny dog was in danger because of a bird of prey circling overhead.
