Could (s)he be breeding?

This yard is not "ravenmatch.com"

Most of the year the Raven perch in the tops of pines around the property but haven't become aggressive even when they had nests near the house.

Maybe DandyLion, stealthy hunter and nimble tree climber, climbed too close to the nest or the ravens have nested closer to the house this year.

Can I throw rocks at the Ravin" Raven? Protected species no doubt.

Hmm, I suppose you can throw rocks at protected species as long as you don't hit them.

I don't know about ravens, but eagles can be a problem. I know one took a friend's cat when they were out in the desert. Now we have them in Pa. Bluejays are protected for some reason known only to the Game Commission Gods.

I suppose check your local laws. I just read that you can't trap ravens and crows but think that was Canada. Here you just shoot crows.

African violets - no one cares if they die out (trying to include the topic).

The Raven has calmed down.
I believe he/she has a nest where they always have a nest, in the pines tree about 300 ft from the house.
I think either Dandy Lion or the dogs may have been snooping around in that area while DH was cleaning out weeds yesterday morning.
The Raven may have come to our house to tell us to stay away from his house.
It is quiet today.
Ravens don't eat African Violets (on topic)
