Reports from ‘H’ for Bird World

17 August 2024

Hello Everyone,

The reports that ‘H’ sends missed me by a few minutes as I had to turn the computer off early to get to the Halifax Airport. She spent much time observing the nests, and I didn’t want you to miss her observations!

8/16  Fortis Exshaw osprey nest:  A day in the life for this osprey family:  Very early this morning one of the fledglings flew from the t-perch and picked up a leftover fish and had a nice breakfast.  Seven new fish were brought to the nest today, including two from Louise!  Louise was first seen at 1008 when she landed for a quick on-and-off the nest.  Then the intruder soon  landed and prevented another osprey from landing (we couldn’t tell who).  After Harvie’s third fish delivery of the day, the intruder landed and stood on the nest for a couple of minutes as a juvenile ate.  An adult did a close fly-over and the intruder left.  From 1028 to 1055, the intruder was on and off the nest a few times, and twice prevented another osprey from landing, including one carrying a fish.  At 1109, the intruder landed, a juvie quickly flew to the nest from the t-perch, and flushed her off the nest!  At 1131 the Intruder landed again, and Harvie flew to the nest and ejected her.  Getting rid of the intruder was becoming a family affair.  Louise delivered a fish to one of her youngsters at 1309.  Louise’s crop was a bit hollow.  She went and grabbed another fish and brought it to another juvie at 1319.  Wonderful Louise, now go grab a fish for yourself!  The intruder buzzed the nest at 1346 and 1357.  At 1524 a juvie on the nest prevented the intruder from landing, but she circled around and landed on the nest anyway.  The juvenile then flapped and ejected her!  At 1656 the intruder was on the nest when an osprey did a close fly-over, and when the osprey approached again, the intruder quickly flew off.  Then it was time for the intruder to do her evening dive-bombing.  From 19:39:22 to 19:44:02 the intruder dive-bombed the lone fledgling on the nest 11 times.  The juvie did not leave the nest, but just kept her eyes on the intruder and pancaked each time the intruder approached.  Only once did there appear to be some slight contact from the intruder’s talons.  The intruder then made herself at home on the angled nest perch.  At 1948 she buzzed the chick on the nest and flew away.  The three siblings were all next to each other on the t-perch as darkness fell.  

8/16 Osoyoos osprey nest:  Both chicks spent some time in the nest waiting for fish today.  At 1212, Olsen delivered a large partial fish, and Soo grabbed it.  We thought she was going to provide a feeding, but she flew off with the fish instead.  I didn’t see any more fish delivered until 1951.  Olsen brought a small whole fish that was grabbed by Chick 1.  Olsen returned at 2003 with another nice sized whole fish for Chick 2.  Both chicks had their crops filled for the night!

Thanks so much ‘H’ and thank you Fortis-Exshaw for both cameras at Osoyoos and at Canmore.
