It's been years since I've seen a blue jay. I recall they used to be common, here.
I haven't heard an owl in a long time, either. I remember hearing their call fairly regularly, when I was younger. Though I rarely caught sight of one. The plastic owls still do a good job of warding away the pigeons, though.
Mocking birds are rare, now. There was a time when I hated that breed with a passion because they woke me up at 7AM on weekends.
