Five peregrine falcon chicks fly at Acadia, but one nest fails

UPDATE 8/01/2017: Park today announces that trails associated with the Precipice, Jordan Cliffs and Valley Cove will reopen on Thursday, Aug. 3, after five peregrine falcon chicks fledged this year — down from 11 in 2016. Trails were closed on March 17.

Five peregrine falcon checks have fledged at nests at two sites in Acadia National Park this year, but for unknown reasons a nest failed at a third site that has yielded chicks in recent years, a biologist at the park said Friday.

Bruce Connery, wildlife biologist at Acadia, said there was a pair of adult falcons at Jordan Cliffs and it is believed they started a nest but then one of the adults disappeared around the middle of June, and the nest failed. Connery said he does not know why the nest at the Jordan Cliffs failed but he said it was not related to the chicks or the nesting.

“My guess would be that one of the adults either left or was killed by a predator like a great horned owl,” Connery said.

On the positive side, the peregrine falcon chicks at the Precipice and Valley Cove have been flying since about July 1, and seemed alert and healthy when they were spotted by researchers, he said. At least one chick at each of the two sites was flying before the others, he said. “They are all flying now and they are doing great,” he said.

Three peregrine falcon chicks fledged at the Precipice and two at Valley Cove, he said.

The park usually waits for the peregrine falcon chicks to fly for five weeks before reopening trails, including the wildly popular Precipice Trail, that are closed in the early spring each year to protect the nesting falcons and chicks. The trails opened July 29 last year and usually open by early August each year.

Connery said the nest failure at the Jordan Cliffs was disappointing because the birds were there and everything seemed to be going along pretty well.

“It would be more understandable if we knew what caused it to fail,” he said, such as the male being attracted to another place.

“We just know we started seeing only one adult …. There was no real rhyme or reason to why it happened.”

Male and female adult peregrines both play vital roles in nesting. Females usually lay eggs in early spring and females incubate the eggs while males hunt and bring food to their mates, according to the web site of the Chesapeake Bay Field Office of the U.S. Fish and Wildlife Service.

Researchers at Acadia don’t know if it was the male or female adult peregrine that disappeared because the feathers of both sexes are mostly similar, but Connery said he would guess that it was the male that left or was killed.

Connery said he was pretty positive it was a “natural event” that caused the nest to fail. He said there is no evidence that human interference was a factor in the nest failure.

The peregrine falcon has “great” year in Acadia, 11 chicks fly

UPDATE 7/29/2016: Park today announces reopening of Precipice, Jordan Cliffs and parts of Valley Cove Trails, and closure of 1-mile section of Valley Cove Trail between Flying Mountain and Man o’ War Brook because of deteriorating trail conditions.

A biologist at Acadia National Park said several popular hiking trails at Acadia National Park should open by early next week, following “a great” year for the peregrine falcon at the park.

Bruce Connery, wildlife biologist at Acadia, said 11 peregrine falcon chicks fledged, or took their first flight, at the park’s three main nesting sites this year. That’s up from 7 for each of the prior two years at those sites.

He said the peregrine falcon nests at the Precipice on the east face of Champlain Mountain and Jordan Cliffs each produced four fledged falcons and the nest at Valley Cove, three.

“It is great,” he said in an interview on Wednesday. “We usually have good success at one site, sometimes two. It is a rare to have that kind of success at three sites.”

He said there was also a chick of the peregrine falcon at Ironbound Island this year with a photo taken by the Bar Harbor Whale Watch Co. The park holds a conservation easement on Ironbound, a privately owned island in Frenchman Bay.

This trail closure sign on the Orange & Black Path, shown in early July, will soon be coming down.

The Precipice Trail, the Jordan Cliffs Trail, part of the Orange & Black Path and the Valley Cove Trail, which were closed early this spring to protect the falcon chicks, should all open maybe this weekend or by early next week, he said. The trails usually do open in early August every year.

The park has not officially announced the date for reopening the trails and trail crews still need to approve some trail sections for safety reasons for hikers, he said. The park announced the trail closures in March. Continue reading

Endangered falcons take the stage at Acadia National Park

Endangered falcons gave birth to 11 chicks this year at Acadia National Park and now are putting on a show for hundreds of visitors to the park.

Park Ranger Andrew Wolfgang shows visitors the location of the endangered falcons and their nest during peregrine watch in Acadia National Park.

On Saturday alone, about 160 people stopped to catch the action of  the state-listed endangered falcons  at a “peregrine watch” site in the Precipice Trail parking area below a nest high on the east face of Champlain Mountain.

“We got a bird up,” said Park Ranger Andrew Wolfgang, pointing to the cliffs when one of the endangered falcons flew back to the nest after a brief absence. “It’s a really nice look at an adult in this scope right now.”

Wolfgang and Samuel Ruano, a peregrine falcon interpretive guide and raptor intern, supervised the use of two spotting scopes that allow visitors some excellent views of the peregrine falcons. Wolfgang and Ruano also spoke frequently to visitors about the history of the peregrines in the park and the need to temporarily close popular hiking trails to give the nestlings time to mature.

With the scopes, visitors could clearly see a peregrine falcon perched upright on the cliff face outside the nest or even the nestlings themselves.

“Amazing,” said Keith Spencer, a grade 7 English teacher in the public schools of Everett, MA, after he looked through the scope and saw a falcon. Continue reading

Look, up on the Precipice of Acadia – peregrine falcons!

UPDATE 8/6/15: The Precipice, Jordan Cliffs and Valley Cove Trails opened today, according to the official park news release.

While we wait for the Precipice Trail in Acadia National Park to reopen any day now, and as a follow-up to our blog post on the 7 peregrine falcon chicks that fledged this year, here are some never-before publicized photos of peregrine falcons, taken by Erickson Smith, biological science technician with the park.

7 peregrine falcon chicks fledge at Acadia National Park

UPDATE 8/6/15: Precipice, Jordan Cliffs and Valley Cove Trails reopened.

UPDATE 7/31/15: Statistics provided by the park state that in 2014, there were 9 peregrine falcon chicks hatched at Acadia including 1 chick at Jordan Cliffs, 2 at Ironbound Island, 4 at the Precipice and 2 at Valley Cove.

A biologist at Acadia National Park said he is pleased that 7 peregrine falcon chicks fledged at the park this year and that popular hiking trails in the nesting areas should reopen around the first week of August.

Bruce Connery, wildlife biologist at Acadia, said the Precipice on the east face of Champlain Mountain is now home to three fledged peregrine falcon chicks; the Jordan Cliffs, two; and Valley Cove cliffs above Somes Sound, also two.

The Precipice Trail, the Jordan Cliffs Trail, part of the Orange & Black Path and the Valley Cove Trail, which were closed early this spring to protect the peregrine falcon chicks, should all open in early August as is usual each year following the falcon nesting season, he said.

The park has not officially announced the date for reopening the trails and still needs to check some trail sections for safety reasons for hikers, he said.

“We are still watching chicks,” he added. “They are getting to be pretty good fliers but they still have a ways to go. They still all come back to the cliff every night. They are dependent on it. They seem to still be pretty much in a group dynamic. They go off for a little bit, but an hour later they will be back perched within 20 to 50 feet from each other. That cliff is still important to them.”

He said the number of fledged chicks is around average for the park.

“It is right in the middle,” he said. “It’s pretty much what we should hope for and expect.”

Unlike last year, Connery said, no peregrine falcon chicks were likely born this year on Ironbound Island, which is located in the park’s legislative area and is protected with a park conservation easement.

“It’s hard to say,” he said. “Some people said they saw them but we never saw them. We were only out four times. If you pick the wrong day, you could be off. I don’t know. It seems odd we would not have seen them if they had chicks but it is possible.”

Also, there were no peregrine falcon chicks on the Beech Cliffs above Echo Lake, a fifth location where falcons have nested in the past.

According to Erickson Smith, biological science technician at the park, there were 9 peregrine falcon chicks hatched at Acadia in 2014 including 1 chick at Jordan Cliffs, 2 at Ironbound Island, 4 at the Precipice and 2 at Valley Cove.
