Here’s a “baby picture” from the University of Pittsburgh peregrine falcon nest this morning: three little birds calling for food.
At the Gulf Tower it looks like only one of the five eggs produced a chick. We’ll continue to look for another egg to hatch but that may be all for this year.
Last year Tasha2 hatched only two out of five eggs, probably due to her age. We don’t know when she was born – she was unbanded when she arrived in 1998 – but she is at least 13 years old, not young for a peregrine. Dr. Todd Katzner of the National Aviary remarked that senescence is common in raptors. It’s not unexpected that they become less productive over the years.
