We were in Invermere last weekend. I spent some time watching a family of osprey on the water. This adult perched in this tree and made a couple of passes over a pond but no dives for fish. They looked pretty fantastic in the evening sunshine so I wasn’t too disappointed.
The pair of Ospreys who summer on the Castle Junction bridge’s nest raised two chicks through adolescence this year. When I spent a day watching them in August that meant there were four of these raptors, now all very close to the same size, interacting with one another on and around the bridge area. Flying, fishing, chasing and fighting over fish dominated the moments of action amid a lot of time spent perching over the river up in the trees that line that stretch of the Bow River.
I spied this Osprey when it alighted on a weathered log with a freshly caught meal. By the time I walked a few hundred metres so that I was directly across the river from the bird, it was no longer alone. Ospreys have excellent vision, roughly twice the distance capabilities of humans, so it was no surprise that company arrived quickly. Another Osprey landed close by, shrilly announcing its arrival and crying out for a share of the sushi. The successful fisher had no interest in sharing and resisted all advances from the other to do so.
Over the next four hours, I watched this bird defend its prize from sneaky grabs for a scrap, frustrated attacks, a couple of near dive-bombs and outright theft! Throughout, the Osprey nibbled away on the fish – whether another bird was nearby or not. The other Osprey never ganged up on their family member but I’m pretty sure two of the three made individual advances.
With the repeated flybys the interloping Ospreys gave me some great opportunities for in flight shots that were interesting and new for my library. The low to ground shots in particular.
The birds were aware of my presence, I didn’t blend in with the rocks on the shoreline. I didn’t move around much and, with the river between us, I felt confident that I was not impacting their behaviour and so I enjoyed the opportunity to watch the family dynamics play out.
Several times the Osprey clutched the fish in one talon and looked to be getting ready to fly. That didn’t happen – the bird didn’t stray more than a couple of metres from the log and stayed on it for most of the time. That made me suspect this was an adolescent with little experience flying with fish but given the size, and the fact that it had caught the fish in the first place, I’m definitely not sure.
Steadily the Osprey worked away on dinner, despite the numerous distractions, and finally finished all but the smallest scraps. Shortly after finishing the Osprey flew off down the river. It flew across my sight line affording me a nice flight series – a fun little reward after four hours crouching among the rocks. I watched it all the way back to the nest where it few around a couple of times before I lost sight of it. I hiked back to the bridge and came back to the shoreline a short stone’s throw from the Ospreys new perch. Again, it took note of me and then continued looking down the river and up at the nest. Several minutes went by before the bird launched and flew up to the nest.
The pair of Ospreys I photographed in the Banff National Park a couple of weeks ago spent most of the afternoon with her on the nest and him perched high in trees over the Bow River. I waited a couple of hours for one of them to dive into the water for a fish.
It happened once, and it was fast. I missed the descent and the initial contact with the water. That bugged me but I got locked in once he surfaced.
I hoped to see a fish in his clutches but when his talons were out of the water and visible, there was no such luck – for them or me. It was interesting to watch the lifting into the air so I was not dismayed in any real way.
Flying past me, I waited to see where the next perch would be. I wanted to see if I would continue to be in a good location for the next dive. The Osprey had other ideas, and flew upriver, disappearing around a bend several hundred metres away. I watched that bend for a little while, in case there was a return flight, but ended the day shortly after that and headed home.
I watched this osprey bathe in a shallow stretch of the Bow River in the Banff National Park on the weekend. The splashing around and dunking under water reminded me of my son when he’s having a soak in the bathtub.
After delivering a fish to his mate, he flew off, gliding under the bridge the nest is built on top of.
He took a break to soak for a few minutes and then dry out his feathers for a couple more.
After a long shake, the Osprey flew back to a high point to better survey the water.
