From the City Birder:
We went back around 12:15 this afternoon and parks staff were scrambling to get a box in which to put one of the little guys who moments earlier had flown off the nest. He glided north across Hoyt Avenue North - into the trees that surround a small section of paved area that people use as a volley ball court...
There was a volley ball game happening and the only person to notice any of the chaos was a young boy of about 10 years old. Fortunately, the little fledge got himself to the ground and was nicely situated in the strip of land between the two fences - it's about 5 feet wide and 50 feet long and overgrown with grass and weeds. However, he was very close to 21st Street and if the volleyball players had realized he was there they could have easily spooked him out into traffic. So, the little guy was boxed up, put in the truck, and the rangers were called.
