Matthew Wills persistence paid off, finding Raven fledglings in the Bush Terminal area
.Its likely Kings first evident nesting ,a historical event.
There were some observation last year pf a flock in the same area but I'm not sure if those ravens were observed fledglings.
Any way, here is Matthews posting on his blog.
