This shows the location of the nest bellow my balcony. Note that there is little head room; just enough for a bird to fly and maneuver in.
Here is the "peep hole" for us humans to get a look at the nest.
I decided to get involved an help out. I took a nightcrawler from our worm keeper (we are outdoors people and therefore go fishing), and tossed it under the balcony. The mother took notice and "accepted" my gift.
Gummy worms anyone?
It is often reported that parenting birds can and will attack suspected intruders including people who come too close. So far I have been spared of any attacks, but they have yet to get used to my presence when I do my yard work duties and get too close. They flee when I come near or start the lawnmower.
