Visited the same way I did on 8/14 and saw the same action. The male was also there and because of that the chick vocalized almost nonstop. Its calls are noticeably more high-pitched and excited than those of the adults. This time, I got a better photo of the chick in midair above the nest. The male was looking on from the side. Any time now.

Visited this evening and stayed for half an hour. I no sooner arrived and had my gear in place than I looked at the nest and watched as the juvenile started to flap and at one point go airborne. Its parents weren't around. The bird did this for about 5 minutes before it settled back down into the nest and rested. I never saw it flap again. It was thrilling to watch, and I look forward to seeing more of the same. Please see photo #17. Again, the photos are out of order.

I visited before sunset. Both the female and chick were in the nest. There was no sign of the male. It looked like the female was shading the chick even though the sun was behind it. Moments later, the chick went up on the rim (first time I'd seen it there) and vacuated. Then the female, which may have already eaten, fed small pieces of fish to the chick. The fish had probably been delivered earlier by the male. According to my calculations, the chick should fledge within the next week or so. We'll keep our fingers crossed. It'll be exciting to see it fly.

Visited in the a.m. If memory serves me, both adults buzzed me. Though the lighting was tough, I did my best to capture them landing and settling on a power pole close to where I was standing. The chick was in the nest. I wrote in my blog that the presence of open perches near an Osprey nest is a plus. This photo seems to bear that out.

Visited before dark. Because of ongoing construction, was able get out on Rossmoyne Rd. (higher ground) and shoot. The chick is getting big and looks healthy. Photo #16 shows female and chick.

Visited several times this a.m. On the first visit, the female was on the nest and vocalizing, but there was no sign of the chick(s). On the second visit I got great looks at the growing chick. It's clear there's only one. I haven't seen the male since 7/5.

Visted in the evening. The female vocalized much and buzzed me once. No sign of the male or chick(s). I entered 6/15 as the clutch hatching date. That's an educated guess.

Visited in the evening. The male delivered a headless fish to the nest, and for the first time I observed the female feeding pieces of it to a chick. I could just make out its head and beak. It appears from my photos that there's only 1 chick in the nest. I provided a close-up of the interaction in photo #14.

Visited in the evening. Both male and female were there. The female was on the nest and the male was nearby. The male then left and headed east as he often does. After a while, the female buzzed me and returned to the nest. This has happened several times before. If anyone's concerned, I never approach the nest and always stay on private property some distance away.

Visited this evening and arrived just as the male brought a fish to the nest. Wasn't prepared to shoot but did manage to get a good shot of the pair in the nest. Judging from what I've observed, the way the pair sit in the nest, etc., I think there are chicks there. I looked for feeding behavior tonight (parent feeding chicks) but it wasn't clear if that were happening.

The female is spending more time on the rim and less time in the bowl. I may have observed some feeding activity recently but can't confirm.

Visited in the early evening. I managed to catch the male delivering a fish to the nest (photo #10). He'd already eaten its head. It appears the female is spending less time in the nest. I watched as the male flew off and headed east. Then the female flew from the nest and wound up almost above me (photo #9). She then headed back to the nest.

Visited in the early evening. The female was alone in the nest. Before too long, the male arrived. After a bit, she appeared to hound him to go get food. Several times she actually left the nest and flew to him as he perched nearby. Were there now young in the nest, I thought. Each time, he left his perch only to return. Finally, and after this happened several times, he left altogether, flying off in the direction of the Susquehanna. Fortunately for me, I was able to get a few good flight shots as he flew around. Also fortunately for me, there was great golden hour light when I took them.

Observed nest this a.m. The male was on a tear bringing nesting material to the nest. This marks the first time that I've seen an Osprey carry nesting material to a nest in one foot. From what I've observed, Ospreys always use both feet. Then they switch to one foot right before the drop-off and right over the nest. See the 5th photo. Photos aren't placed in order here sometimes.

Visited early a.m. With sun behind nest, could only get silhouettes of nest and either bird in flight. At one point both adults were on nest. One was on the rim while the other appeared to shade young. Having said that, I don't think there are any young just yet.

I took photo #4 on 5/20. It provides a closer view (and in better light).

We observed the nest this evening and heard the female vocalize. We fully expected the male to show up. The female has been deep in the nest for a week or so. There's no question she's on eggs.

Farm pond below. A half mile to Yellow Breeches Creek and 4-5 miles to the Susquehanna River.

05/04/2022 by Dave Gibson
The nest has grown. We observed the male add both natural and manmade materials to the nest as the female stayed put.

Adult arrival on 4/15 is an educated guess. The nest is above a farm pond and is close to Yellow Breeches Creek and the Susquehanna River.
