Hello everyone!<\/p>\n\n\n\n

We are excited to share with you an update on our nest monitoring of the common murres and cormorants at Yaquina Head Outstanding Natural Area (YHONA). Although our updates were on hiatus in 2020, we are happy to report were able to conduct monitoring. However, there was colony wide reproductive failure as a result of high rates of predator disturbance (bald eagles, 0.58\/hour). At one point 15 bald eagles simultaneously hunting at Yaquina Head; a group size that has not been recorded at the site before or since.<\/p>\n\n\n\n

This year, we began monitoring efforts in late May. In early July we were monitoring 161 common murre nests, 93 of which had eggs, and 11 of which had chicks. The first chicks hatched on June 28th on Lower Colony Rock and Satellite Rock.<\/p>\n\n\n\n

Eagle Disturbances<\/h2>\n\n\n\n

As observed in recent years, bald eagle disturbances were fairly frequent within our Colony Rock nesting plots during the months of May and June. Beginning in July we have seen a noticeable decrease in disturbances. From June 2 – 30 June, 2021 we recorded 41 disturbances. Murres nesting in larger colonies appear to be holding their ground in all plots except for the top eastern half of Colony Rock where adult\/sub-adult bald eagles perch periodically, allowing for gulls and turkey vultures to pillage unattended eggs. Flat Top Rock has remained nearly empty for the duration of the breeding season and was not included in this year’s monitoring efforts.<\/p>\n\n\n\n

Cormorants<\/h2>\n\n\n\n

Along with common murre monitoring, we are also monitoring Brandt\u2019s and pelagic cormorants. We are currently monitoring 22 Brandt\u2019s cormorant nests and 37 pelagic cormorant nests. Chicks began hatching the week of July 5th and the majority of our nests for both species now have chicks.<\/p>\n\n\n\n

We look forward to updating you on the success of our nests in August.<\/p>\n\n\n\n

This year, we\u2019re delighted to have the addition of several new (and returning) lab members including Laney Klunis, a 2021 Research Experience for Undergraduates Intern from California State University Monterey Bay; Edward Kim, the 2021 Intern at Bureau of Land Management; Alyssa Nelson, USFWS Intern and former undergraduate lab member; and Noah Dolinajec, student in the Graduate Certificate in Wildlife Management (OSU) program are conducting field work for the 2021 YHONA season. We are pleased to be up and running with a full field team this year!<\/pre>\n\n\n\n
