I've been whistling twice a day to summon my minions, but some days I just can't whistle.

I don't want to just leave the food out, I really enjoy watching them swoop in.

Has anyone successfully changed their call?

I tried playing a recording of my whistle but they didn't seem to recognize it.

Suggestions for ways to summon them are welcome.

I've befriended a murder of crows and feed them twice a day in my yard.

When do fledglings usually appear in Seattle?
