“We typically start seeing these species of geese show up in early to mid-February and peaking mid- to late March,” said Tyler Archibald, who works at the Fort Boise Wildlife Management Area where the birds end up.
In a news release from Idaho Fish and Game, Archibald said the birds arrive fairly suddenly — and leave just as abruptly.
“Usually by about mid-April, they’re all gone,” Archibald said.
Archibald said the geese are “staging” at the wildlife area northwest of Parma near the Oregon border after spending the winter in Central California. From Idaho, they’ll head to northern Alaska and Siberia to nest, he said.
The geese first arrived in the early 1990s, and the gaggle has steadily grown since then, Fish and Game officials said.
“In the eight years I’ve been here, we’ve consistently had probably around 40,000 geese each year,” Archibald said.
The Fort Boise WMA, which is open year-round, is an hour drive from Boise. Access is free.
The area is popular for hunting and bird watching, and Archibald said a wildlife viewing platform that was installed in recent years offers a great view of the geese.
