Hard to say goodbye

Maya and 33 are still here in Manton Bay! Last year, 33 left on the same day as the last juvenile, and Maya left the day after. This year the last juvenile left five days ago! This is why we’re slightly surprised that they have stayed this long. Not that we mind, though, it’s great to still have them!

We answered the question of what triggers the juveniles’ instinct to migrate, as the three from Manton Bay this season left at the usual 14 weeks old, which happened to fall a lot earlier in the year than is typical. Based on this, it would seem to be their age and not the time of year that prompts them to leave. However, it looks like it’s different for the adults, in that the time of year plays a more important role to them, as their migrating instinct doesn’t seem to be triggered by the lack of juveniles! This could mean that Maya and 33 remain in the area for the next week, as their departure dates last year were the 2nd and 3rd September. Maya’s previous departure dates have always been in September, the latest being the 12th. It’s just that generally the juveniles have left only a day or two before.

The pair seem to be enjoying their time alone together, as you can see below in Dave Cole’s excellent video, filmed on Sunday 28th August. This beautiful video shows the two adult ospreys bringing in fish and sticks, and just hanging around together now that their chicks have gone. They should be thinking about migrating very soon, so this may be the last footage we have of them this season. Thank you Dave for this!

Thanks also to Dave Cole for these photographs of Maya and 33 on the T-perch. Maya caught this fish and she’s not keen on sharing!

    It’s an interesting comparison that you make between the juvenile’s and the adult’s leaving dates. Also, presumably the juveniles leave fully fuelled whereas the adults would benefit by using the extra time to replenish their depleted fat reserves, as well as strengthening their pair-bonding. But there’s clearly an overwhelming stimulus that drives them to leave in September.

    Interestingly, the Dyfi fledglings migrate 10 days earlier than yours:

    “At 88 days, Tegid migrated bang-on the average for Dyfi birds.”

    It has been wonderful to follow these lovely birds from their arrival this year. They are fascinating.

    What wonderful filming, second to none. This insight into the life of the ospreys has kept me riveted all summer and i shall miss them immensely.
    Thank you thank you
