KEMPTON, Pa. — Almost 1,000 migrating raptors have been recorded so far during Hawk Mountain's official spring migration count.
“Since the rain finally allowed the trainees to begin counting, 15 raptor species have been observed from the rocks,” according to a Thursday news release from the Berks County sanctuary.
“Our broad-winged hawk peak occurred on April 19 when 101 broad-wings were tallied moving high over the lookout.”
Staff and volunteers at the sanctuary have monitored the spring raptor migration since the 1960s, with an average of about 1,000 raptors each 45-day season, according to the organization’s website.
One-day peak counts can reach more than 100 birds in mid- to late-April. This season’s count continues through May 15.
There were 948 raptors recorded as of May 4.
“Eagles have put on some notable pushes, with 66 bald eagles appearing to migrate along with one subadult golden eagle that passed the lookout on April 11,” officials said.
In addition to raptors, spotters have recorded blue-headed vireos and black and white warblers.
Earlier in the count, double-crested cormorant and common loon provided some excellent looks as they pushed north along with the occasional great-blue heron and migrating gull.Hawk Mountain
“Last week added wood thrush, ovenbird, Baltimore oriole to the Sanctuary count along with a strong push of neotropical migrants starting April 28th,” officials said.
“Expect peak songbird migration this week, and then the flight will slow down as the local breeders claim their territories.
“Earlier in the count, double-crested cormorant and common loon provided some excellent looks as they pushed north along with the occasional great-blue heron and migrating gull.”
Last year, the spring migration count ended with just shy of 1,200 birds of prey recorded — 25% above the 10-year average.
