For many raptors courtship season has given way to incubation but this recent video of a western marsh harrier in England reminds me that fancy flying is an important part of choosing a mate. Here are four species going all out in the air.
Golden eagle (Aquila chrysaetos) Video description: The dizzying “sky-dancing” of a Golden Eagle is a territorial and courtship display. They dive from great heights and can reach nearly 200 miles per hour.

Dana Nesiti visits Schenley Park every day to record the progress of the great horned owl family: mother, father, Muppet who was rescued in Feb and returned in March, and Sibling. (Read the back story in this 28 March article: Schenley Park Owl Update)
On Monday 31 March, Sibling made a big leap in development that allowed Dana to photograph three family members in one shot!

Dana describes how big a deal this was:
4/1/2025. In today’s episode of the owlet’s development and behavioral series we find the owlets eating before daylight and then puffing themselves up against the cold wind. Video is a bit over 5 minutes.
Confirming with citizen scientist friends that yesterday’s [31 March] capture of Sibling finally making it up into the canopy with the adult and Muppet was a first for it. Today [1 April] was the first we saw it feeding with Muppet and the adult.
Yesterday was windy and cold so the two siblings ate and then puffed up and huddled together. Here’s Dana’s five-minute video of their morning activities.

This week Dana Nesiti is having a great time observing Schenley Park’s great horned owl family. Yesterday was exceptional when he found and photographed all four family members and confirmed the well-being of both youngsters. See the complete story in Dana’s Facebook post here.

This year’s two owlets are celebrities, easy to tell apart because they have different markings and even different personalities.

Muppet a.k.a. “Muppet the Marauder” is the whiter of the two youngsters. She fell 100′ from the nest on 27 February and was rescued and taken to Tamarack Wildlife Center where she acquired her nickname. Tamarack returned her to Schenley Park on 11 March where she branched for a couple of days and soon began making short flights from branch to branch and tree to tree. Tamarack says she has the personality of an avid explorer. At this point Muppet has been flying for about two weeks.
Sibling, whose sex is unknown, stayed in the nest until 24 March and was seen making short flights the next day. Sibling is cautious compared to Muppet. Dana captured him/her making a flying leap.
True to her personality Muppet flew much sooner than I expected. Sibling more is in line with my flight-date predictions.
If you want to find the owls in Schenley Park I suggest you look for the photographers or listen for blue jays. Both are good indications that an owl is nearby.

Schenley Owlet flying
The Schenley Park owlet, who spent two weeks in rehab at Tamarack and came home on 11 March, has been making fast progress. Many have seen her roosting in trees this week and assume she must have flown to get there, but we never see it. She only moves in the dark. Fortunately, Dana Nesiti captured a video of her in flight before sunrise on Tuesday. He slowed down the video so you can see her.

Pitt peregrines not incubating yet
Carla laid two eggs at the Cathedral of Learning peregrine nest on 16 and 18 March and a third egg is due this evening.
However, we’ve seen both parents cover the eggs and we know incubation begins when the next to last egg is laid. Are they incubating? Is Carla going to lay only 3 eggs?
As of this morning, 20 March, we have nighttime evidence that the peregrines are not incubating yet. Both were off the eggs the majority of the time last night as seen in this time lapse video.
Nighttime timelapse at Pitt peregrine nest, 19 March 7pm to 20 March 2025 7am ()
When peregrines are truly incubating they open the feathers that cover their brood patches before laying down to place their skin on the eggs. If they don’t, those feathers keep the eggs from reaching incubation temperature.
On the falconcam it is impossible to see if their skin is touching eggs but we can tell if they are opening the feathers. Watch for them to bob their bodies before they lay down. Ecco does this in a more exaggerated way than Carla.
Speaking of Ecco, did you notice that he relieved Carla around 3am? The literature says that the female incubates all night, but not last night. Peregrines can always surprise us.
When a female peregrine is getting ready to lay eggs she spends the night at the nest ledge. As egg laying becomes imminent she doesn’t have far to go to crouch over the scrape.
Last night Carla spent five hours at the nest and, from the start Ecco encouraged her to do so.
This Day-in-a-Minute timelapse video shows nest activity from 10:30 on Saturday night through 7:00am Sunday morning, 15-16 March, as follows:
15 March 2025: The nest is empty from sunset until 10:30pm, not shown in the video.
When Ecco arrives he pops in and out so fast that you might not realize it’s him. Carla arrives soon after.
Carla stands on the gravel or the green perch for most of the night; she leaves at 4:40am.
A few minutes later Ecco arrives, checks the scrape and spends a while on the green perch.
The real time video clip below shows the most interesting segments. With audio on you can hear Carla calling before she leaves the nest, perhaps wailing to Ecco for a snack. After a short gap with no peregrines, Ecco comes to the nest.
I’ve seen a lot of ravens in the past two weeks — 11 in Minnesota, two as we landed at Pittsburgh airport, and one over Aspinwall on Tuesday. When I found Vance Crofoot’s 3-minute video explaining raven territories I was fascinated.
Immature ravens spend 3 to 4 years in large flocks of young ravens. On reaching adulthood, ravens pick a mate and go off to claim a territory.
Adult pairs display their territorial boundary by flying along the border.
Ravens know their neighbors and will sometimes fly with them along the mutual border.
Ravens help their neighbors drive out predatory threats.
Other ravens are not allowed to land in an adult pair’s territory. If they do they are challenged.
When a pair has chicks they aggressively drive out predators.
Once the chicks can fly, neighboring families meet up for “play dates” with their kids.
Youngsters also can bring friends home to play with.
Juvenile ravens stay with their parents for about 7 months. At the end of that time their parents aggressively drive them out of the territory.
The first comment on the video points out how different ravens are from crows!
Very informative! It’s interesting that the intergenerational behaviour is different from crows whose juveniles hang around longer and actively assist their parents in raising the next chicks and fledglings. The ravens’ cooperative behaviours are very well adapted to their needs and types of threats.
Ravens have moral standards, they understand fair play, and when someone breaks their trust they refuse to deal with them again. Ravens hate a cheater.
We know this because researchers conducted a trading experiment in 2017 in which they built trust with ravens (Corvus corax). When a raven offered bread, the human gave him his favorite food, cheese.
Then one of the researchers accepted the bread but ate the cheese she was supposed to give to the raven, in effect saying, “Hah Hah Hah! Fooled you!”
The ravens were outraged! Find out what happened next in this vintage article.

13 February 2025
Though it’s been cold and snowy, Chad+Chris Saladin are busy monitoring peregrine territories in northeastern Ohio to see who’s present and who is not.
On Sunday 9 February they caught up with Gusto, the male peregrine who’s been resident at the Hilliard Road Bridge site over the Rocky River since 2021. While Chad took photos Chris captured a video of Gusto watching and preening on a branch, then doing a tap dance on the ice before he took off.
p.s. You probably noticed that Gusto pooted before he took off. Birds typically lighten their load before takeoff by getting rid of useless “baggage.” So they poot before they fly.
Bald eagles are top predators who will eat crow nestlings, fledglings and unwary adults if the opportunity arises, so crows learn from a very young age to watch out for eagles.
Even in the nest young crows hear and see their parents drive off hawks and eagles. In their first year of life, which they spend with their parents, they learn the rules of harassment.
When a lone crow sees an avian predator he perches prominently and calls for reinforcements.
When his buddies arrive the crows work as a mob to drive away the predator.
When the situation is acute and the mob is left behind, a solo crow may harass an eagle even though he’s the only one left. Sometimes he does something daring.
Ten years ago photographer Phoo Chan went to the shore at Seabeck, Washington to photograph the bald eagles who arrive in large number during the midshipman fish run (Porichthys sp). He was very lucky to capture photos of a lone crow riding on an eagle’s back. See more in his article below.
The Eurasian green woodpecker (Picus viridis) is a bit unusual. Instead of drilling trees he spends most of his time on the ground, poking his beak in the soil.
Predominantly [eats] ants, chiefly meadow-dwelling species of genera Formica (winter) and Lasius (spring to autumn); generally, larger ant species preferred. …
Uses bill to sweep away moss, dead leaves, other debris, or snow; pecks funnel-shaped holes up to 12 cm (4.7 in) deep in ground, and procures prey with action of the very long tongue; such holes may be exploited in lengthy and repeated visits. When snow cover heavy, can dig tunnels almost 1m (more than 3 feet) long to reach prey.
These traits may remind you of a North American woodpecker. Though not closely related, our northern flicker (Colaptes auratus) also forages on the ground for ants and shouts in the spring.
