He was at Annie the falcon’s side just seven several hours following the demise of her longtime mate Grinnell final 7 days. He’s been serving to to incubate the a few eggs in the nest on UC Berkeley’s Campanile, at times for an hour and a 50 percent at a time. And he is faithfully searching, even bringing Annie meals in the center of the night time.
Ideal of all, Annie likes this new falcon, distinguished by his injured remaining leg, which hangs minimal when he flies, and a cap of really darkish plumage on his head. They mated in just 24 hours of his arrival at the bell tower past Thursday and have engaged in head bow shows this bonding might preserve the 3 eggs in the nest — the egg-laying is now in excess of — from failure.

“What shocked us was how swiftly he took on parental duties,” reported Sean Peterson, an ornithologist with Cal Falcons, of the new male, aka New Man. “It is very uncommon to see this transpire the most most likely result of a dead member of a breeding pair is clutch abandonment.”
The exhibit of four very important behaviors — head bowing, copulation, incubation and searching — has gained New Male a new name. Now, Cal Falcons is asserting a naming contest, inquiring the community to submit tips by means of its social media channels — Instagram, Fb and Twitter.
The names ought to relate to UC Berkeley. Annie is named soon after Annie Alexander (1867-1950), an explorer, naturalist, paleontological collector and philanthropist who launched the UC Museum of Paleontology and the Museum of Vertebrate Zoology (MVZ). Grinnell’s title came from area biologist and zoologist Joseph Grinnell (1877-1939), MVZ’s first director. Grinnell was Alexander’s preference for the post.
When most of Annie and Grinnell’s 13 chicks did not receive Berkeley-similar names, it is really critical that Annie’s new mate “be anchored to the college,” explained Peterson. “In contrast to the chicks, who shell out the the vast majority of their life absent from campus, Cal is New Guy’s home.”
Cal Falcons’ scientists will pick the top names and expose them Wednesday, April 13. The community then will vote for the profitable title, to be introduced Monday, April 18.
Welcoming a new mate for Annie this shortly right after Grinnell’s demise is challenging folks continue on to leave tributes to him — bouquets, cards, even a Cal Falcons T-shirt — beneath the bell tower.
Nonetheless, “it truly is ordinary and all-natural for Annie to take on a new mate quickly. She only has two imperatives: survival and replica. This is not a negative detail,” reported Mary Malec, a Cal Falcons raptor professional who retrieved Grinnell’s physique from the intersection of Kittredge Street and Shattuck Avenue on March 31.
Grinnell’s system was much too damaged for a entire forensic evaluation by the point out Division of Fish and Wildlife’s Wildlife Overall health Laboratory in Sacramento. Carla Cicero, staff curator of ornithology at the Museum of Vertebrate Zoology on campus, said that the stays rather will be built into a research specimen.
What prompted Grinnell’s death is unknown — this kind of as getting grounded by a rival falcon and then run in excess of by a vehicle, or acquiring hit by a car whilst searching and swooping low— and most likely will stay that way, the researchers said.
But it really is attainable that Annie, if she have been in the air at the time of his demise, saw what occurred to Grinnell, claimed Malec. “It can be really feasible she realized right absent,” she reported. “The tower is only a quarter of a mile away, and she wasn’t in difficult incubation at the time. She was off the nest as a great deal as on.”
The eggs in the nest are predicted to hatch on or close to May 6, “if incubation goes off devoid of a hitch,” said Peterson, “and it seems like everything’s likely nicely ideal now. But there’s a little bit of a buffer around that date, as it’s been a unusual calendar year.”
He claimed the two eggs laid in advance of Grinnell’s loss of life are “pretty much definitely Grinnell’s. The 3rd egg was laid two days soon after Grinnell’s dying and has an not known parentage. Birds can store sperm for up to two months, and we have observed (Annie’s) copulation with New Dude, so the 3rd egg could actually be either males’.”
Dr. Zeka Glucs at the Santa Cruz Predatory Chicken Exploration Team has been amassing feathers from Annie and Grinnell’s chicks for the past two years as section of a research on relatedness amid Bay Space peregrine falcons, so “we will likely accumulate feathers from any chicks that hatch this calendar year and will check out to ascertain paternity,” explained Peterson.
The falcon drama at the Campanile in the course of the past six months is probable to continue on, in one particular way or yet another, in the months and several years to arrive, due to the fact the variety of floaters — non-breeding grownup birds of prey captivated to occupied territories — is growing, explained Malec. For illustration, in California there were two regarded nesting pairs in 1970, when the peregrine was stated as endangered, she said, but there’s a balanced populace of 350 this sort of pairs right now.
Malec and other volunteers counted at least eight different falcons close to the Campanile while Grinnell was hospitalized very last slide immediately after currently being attacked by rival falcons.
A juvenile falcon even entered the nest box this 7 days and then stayed for half an hour on the north ledge, as Annie viewed. New Guy was a floater, also, and was viewed about the Campanile for about two weeks at the end of March, but he didn’t decide a combat.
“They’re all wanting for territories,” reported Malec. “A juvenile will glimpse, even if it won’t be able to breed this 12 months.” Annie and Grinnell defended their nest two times the early morning of Grinnell’s demise.
“If we are not there now, we’ll shortly be at the saturation level, or even above-saturation,” she extra. “The falcons will have to start tolerating and halt preventing just about every other, get a small significantly less sensitive, or the inhabitants is going to drop, since an raise can trigger pressure … and no babies.”
The sight of Annie and New Person peacefully tending their nest is a optimistic one, Peterson mentioned, “and folks have genuinely grown to really like and root for New Guy actually promptly.”
Nevertheless, “it truly is hard for the reason that we pretty much haven’t had time to mourn Grinnell — the exercise with New Person took place so rapidly that we have not experienced time to capture our breath,” he stated. “He form of provides you one thing positive to fixate on, which is awesome, but it can be nonetheless challenging to say goodbye to Grinnell.”
Zeynep Enson, a third-year scholar in environmental sciences and a campus ambassador, admitted that the campus’s falcons “these days have been taking part in with my coronary heart. … Annie and Grinnell will usually be a pair in my and many others’ minds.”
“But a new man pretty much swooped in to help you save the day, … and now we’re all fired up about what the foreseeable future will provide,” she extra.
Malec considerably misses Grinnell, also, but made available this:
“Peregrines are persons. Grinnell was Grinnell. Annie is Annie. And New Guy is a unique hen. It will not make him less of a chicken, but he has a different id, and we will all grow to be hooked up to him, and we will all nevertheless sustain our attachment to Grinnell.”
