4 eggs for Melbourne, Victor is moved outside and other news in Bird World…Monday morning

30 August 2022

What happened to August? It seems as if we blinked and it flew by. Despite the heat there is a look about the leaves on the trees and the wilting of the tomato plants despite their being well watered that is alerting us to the end of summer, not just the calendar. There is another 9 or 10 days before the teachers and students are back to their classrooms in Manitoba. It is a reminder that it is time to get a small delivery of firewood. There is something so cosy about a wood fire on a crisp autumn morning and if August is any indication, autumn will be here in two blinks.

The colour of the light and the water of the pond seemed to be taking on the hues of autumn.

The rain started in the early morning hours of Monday and everything has turned green in the garden again…it is raining so hard! And for once, I am so glad to see it! Monday will be a good day for reading the small pile of books accumulating on my desk.

In the Mailbox:

‘N’ writes: “Do all falcons incubate the eggs the same no matter where they live? Do all ospreys?” Oh, what an interesting question! I am not a specialist on incubation, the term used for the behaviour whereby adult birds keep the eggs warm until they hatch. My experience watching the nests of different species is that birds are very individualistic and even within a single species, the attention that they give to their incubation duties varies. I found a paper that actually discusses the different approaches to this important task. It is not a recent one but it is quite interesting. The author covers some birds that are unknown to me but, I believe the findings and the data can enlighten us as to the full answer to your question, ‘N’.

In the News:

RSPB created an extremely short video about Avian Flu killing the White-tail Eagle chicks on the island of Mull. What is so intriguing is the landscape of the island and the beautiful chicks so alive in the nest. It is clearly not the be all- end all informative presentation but it was nice to see where these eagles live.

Just a couple of months before Avian Flu began killing the White-tailed Eagles on Mull, this beautiful 7 minute video was made showing them on their island setting. Have a watch:

The attempt to rid Gough Island of its House Mouse problem has hit a wall. The eradication of the mice that were biting and killing Tristan Albatross chicks and adults is now being viewed as a failure. Everyone had such high hopes that the island would be rid of these invasive mice but an unknown problem presented itself – the slug. Have a read:

I found an excellent story dealing with the tragedy of the mice and the Tristan Albatross and why the eradication attempt is so important.

In his newsletter, David Hancock of Hancock Wildlife just posted the following information about the Delta 2 nest in British Columbia, Canada: “Firstly, both Ma and DM have gone on their migration. Ma was last seen at the Delta 2 nest/territory on July 25th. DM (taking his new role as Ma’s mate very seriously) hung around for another week keeping an eye on things. He was last seen there on August 1st. Thanks to all who donated to the GoFundMe campaign, as well we received a a few private donations which are greatly appreciated. These donations are going to cover the costs associated with the installation of a sturdy new nest pole and two (2) new cameras at Delta 2.”

Nest News:

It is egg 4 for the Melbourne Peregrine Falcon couple on the ledge of 367 Collins Street! Oh, my goodness. Dad you are going to so hope that the pigeon population of the city is very plentiful!

Here is a video of that last egg being laid:

It was a prey drop and a chance for Dad to get himself acquainted with how you have to wiggle around to get 4 big falcon eggs under so they can stay warm.

It is a lot easier for Mum to get those four eggs tucked in tight. Do you think there will be a 5th?

We have a ways to go before hatch for Melbourne and Diamond might not be finished laying eggs. Incubation is a time for the females to rest. It is going to be very hectic if all the hatch at Melbourne! And exciting.

The Sydney Sea Eagles are developing right to schedule. Their plumage continues to come in and they are picking up sticks in the nest and preening. SE29 is standing and walking better each step. They really are gorgeous. The Monday morning feeding saw both 29 and 30 with nice crops full of fish. I have seen no concerning aggressive behaviour on the part of 29 to 30 that would cause me to worry.

We are about 3 weeks away from hatch watch at Port Lincoln. Mum and Dad continue to take turns incubating. That said, Mum will always have night duty and Dad will provide Mum with her meals.

You would think that Mum would be very stiff incubating the eggs all night. Dad has arrived and is nudging her off so he can have a turn. Mum goes away for her breakfast and a break, returning in about half an hour.

You are doin’ good, Dad.

There has been an unknown male visit Annie in the tower.

There is a notable change in the behaviour of the female Ospreys in the UK this year. Normally they would depart the nest about 10-14 days prior to the fledglings leaving on their migration. This year it appears the majority are choosing to remain on the nest while some or all of the fledglings depart. While we will not know the specific reason, I wonder if it is, in part, due to the raising of these large female chicks and the Mums needing more time to get in top shape. Or could it be that prey is plentiful, the weather is nice in the UK, and they just want to be home for a little longer?

Idris, Telyn, Padarn and Paith are still at the Dyfi Osprey nest in Wales as of Sunday the 28th. Idris has stayed on the perch all night. Pedran was last seen on the 11th of August at 0905.

If you follow Tweed Valley, the three fledglings are going in very diverse directions including Glen who remains on the nest. Kirk is in Ireland having flown south and turning back to the land. Tweed is nearing land in Portugal.

Ruthland is updating us on their second hatch at Manton Bay, 1H2:

Tiger Mozone says that the fledglings need good DNA and luck. 1H2 certainly has great DNA. Let us all hope she has some awfully good luck, too.

1H2’s parents, Blue 33 and Maya, along with older sibling 1H1 were all still at the Manton Bay Nest at Rutland on the 27th and there is no news of either 1H1 or Maya departing since.

Seren was on the Llyn Clywedog nest early this morning and Dylan even popped in for a few minutes to join her later.

It is just incredible. Bonus continues to prove that he is a very special Black Stork! He flew from the nest in Estonia and spent the night in Latvia on the 27th. He has now flown through Lithuania and is in Belarus near Minsk. That was a total of 279 km.

Kaia, Bonus’s foster mother, remains in Belarus in the Prypjat Wetlands near Shestovicy.

So what intrigues me is this. If Kaia remains where she has been for the last several days since she flew north out of the Ukraine, is it possible that Bonus might also wind up in the same wetlands? Or will Bonus fly into the Ukraine? and remain there? or turn back north like Kaia? We should have our answer in a day or two.

Here is the distance shown by Google Maps:

Waba has begun the journey also and the tracker shows that he crossed into Latvia from Estonia on 28 August. He then flew a short distance.

I have received word that Karl II has left the nesting area in the Karula National Forest and has begun his migration. More on that to come tomorrow.

Victor has done so well since Dr Sharpe travelled to the Two Harbours nest on the Channel Islands to take him to be treated for zinc toxicity at the Ojai Raptor Centre. He has now been moved out to the big flight area! It just doesn’t get too much better than this until he is released. Wow. Victor. Way to go!

Looking forward to Lena and Andy at Captiva next year? or Connie and her mate? Window to Wildlife posted a 7 minute video about updates changes to the cameras, etc with some lovely pictures of Lena feeding the wee nestlings last year.

Thank you so much for joining me today. Please take care of yourselves. See you soon.
