Like all of you I have been watching birds in the Southern Hemisphere. Yesterday, the Sulphur Crested Cockatoos were exploring the White Bellied Sea Eagle nest down in the Sydney Olympic Park.
The sea eagles are still enjoying being in the ‘off season’ but spring is arriving in the North and there are lots of happenings ——-everywhere. Too many to try and keep up with! This morning a reader from Brazil who turned me on to Latvian White-Tailed Eagles asked if anything was happening in Canada. I felt a little embarrassed. So here is the condensed version to help you locate several of the streaming cams in Canada. There are many more!
One of the best wildlife sites is Hancock Wildlife Foundation in British Columbia. They support five streaming cams and there are already eggs on the nests. The link to their streaming cam sites is:
Dave Hancock is known for his passionate devotion to the Bald Eagles.
Their site also has a link to several satellite trackers so that you can follow the migration patterns of the banded eagles. Here it is:
And if you are looking for books on Indigenous culture including the Haida, various species of birds, fishing, Indigenous healing, or arts and culture you might want to check out Hancock Publishing. They have a large selection of books that you might not find at your local shop or the one line stores. I was certainly surprised when I first located that link and found a book on the behaviour of the Golden Eagle that I had searched for elsewhere.
And if you don’t know about Dr Christian Sasse, you need to Google his name. He is a passionate photographer who chases eagles around Vancouver. The images he captures are quite incredible. Here is one of his short videos:
You can also join us in Manitoba for the Peregrine Recovery Project. The clock is ticking away. We are, at this very moment, expecting the falcons to arrive here in twenty-two days! I will be keeping you informed here and will be anxiously awaiting fledge when I along with many others join in keeping tabs on these young falcons. The link to that page and the various cameras is here:
The feeder cam at the foot of the Rocky Mountains in Alberta attracts songbirds just like the Cornell Bird Cam at Sapsucker. They also have a live chat feature. Have a peek:
Besides the falcons in Manitoba we also have the polar bear cams up in Churchill, Manitoba but…just to show you the massive number of streaming cams run by one organization, here is a link below that will direct you to any kind of bird or mammal you want to watch:
Oh, welcome to The Daisy Chronicles, a daily update on the life of the little Black Pacific Duck that has made a nest in a White Bellied Sea Eagle nest in the Sydney Olympic Forest. It is Day 13 of incubation. We could be half way to hatch!
Och, witamy w The Daisy Chronicles, codziennej aktualizacji życia małej kaczki Black Pacific, która założyła gniazdo w gnieździe bielika morskiego w lesie olimpijskim w Sydney. Jest 13 dzień inkubacji. Mogliśmy być w połowie drogi do wyklucia!
————————————————————————————-It is 7:44 on the nest in Sydney, Australia and Daisy knew what the weather was going to be today. She got up early, at 4:13:44 to go for a swim and some foraging. The weather news says it will be 36 in Sydney today and it will be hotter on the nest with the direct sunlight at times.
How many times have you checked the weather only to find out that the weather report was wrong? When I was a little girl staying with my grandmother, she would open the front door of her house and ‘sniff’. Then she would declare that it was going to rain. At the time, not knowing anything, I thought she was a witch! How silly was that? But how do birds know the approaching weather?
Some say that the hollow bones of a bird help them determine the barometric pressure and, thus, they are able to anticipate incoming weather. Others say that it is the pressure plates within their ears. Daisy is not a bird but a waterfowl and still she anticipates the changing in temperature, rain, etc. That is because she, also, has hollow bones. Recent research at The University of Western Ontario suggests that birds have an internal barometer. They can tell even the slightest change in barometric pressure and temperature. And, of course, they have these skills because knowing if they should forage or hunt immediately, if rain or snow are coming, are essential to their survival. Researchers at the University tested their ideas by lowering and raising the air pressure inside a specially built wind tunnel. If they lowered the air pressure, the birds would immediately start looking for food and prey. Low pressure means that a storm or rain and winds is approaching. They might even have to find a safe place to stay for hours or even days depending on the strength of the storm. Likewise, if the barometric pressure and temperature rise a bit, the birds will have a reasonable morning in the nest preening before heading out to hunt or forage. Today, Daisy leaves her nest early because she knows that it is going to be very hot during the day and she may need to dabble several times rather than just one long foraging trip.
For those of you who are ‘sort of’ keeping up with Daisy, things have been relatively quiet for a few days. Today is day 13 of brooding. The WBSE ‘Dad’ made a surprise visit to the nest tree last evening at 16:59:24 but as quick as he appeared, he left at 17:03:43. I am sure he thought he would catch whoever was brooding in his nest. But Daisy has been very smart. And with the heat she may stay out foraging or dabbling longer. She landed on the rim of the nest at 19:49:49 but was very cautious looking around before venturing over to her eggs. In fact, she did not actually go over to the nest cup until 19:52, three minutes after arriving.
Daisy is very much aware that the White Bellied Sea Eagles come and go in the forest. Sometimes they stay for a few minutes, other times for many hours. She listens for the vocalizations from the other animals and birds in the forest to let her know if they might be coming. Her survival depends on it.
At 4:13, it is already more than 22 degrees C on the nest. Daisy is anticipating a very hot day. She has decided to go dabbling early before all of the other birds and animals in the forest are awake. You can see from the image below that it is still very dark in the forest. What we are learning is that Daisy, a Black Pacific Duck, can see in the dark better than the WBSE.
In fact, anyone observing this nest is learning a lot. No one can remember a Black Pacific Duck making their nest on a Sea Eagle camera or a place where we could easily observe without threatening the wildlife.
If you look carefully at the image above, you can see Daisy’s tail on the right behind the tree branch. She is just preparing to fly off to the water.
Daisy forages for a little over an hour. She returns to the nest and quickly bets on her eggs to incubate them. She rolls them with her paddle feet carefully and turns in the nest gently.
Daisy returns just after 5am. Sunrise is at 6:05. She knows that the sea eagles often fly into the forest at dawn. In the image below she has heard the sound of ravens. Ravens, you will remember, often chase the sea eagles. She listens carefully for several minutes before settling down.
By 8:30, Daisy has already had visits from at least one Sulphur-Crested Cockatoos and the Ravens were alarming at 8:04. Now the Rainbow Lorikeets can be heard in the forest but I cannot see them on the nest yet.
It is now after 10:00, and the sun is shining on Daisy in the nest. She has already starting panting in order to regulate her temperature.
It will be 36 degrees C in the forest today. It is understood that it is hotter on the nest. Look carefully and you can see Daisy’s bill open. That is her panting. The shade is ever so slowly moving over Daisy but the heat is almost unbearable. Instead of panting slowly, now it is a fast clacking of her bill.
Let us hope that it is way too hot for the sea eagles to be in the forest today. A day without sea eagles is a safe day for Daisy! And it is going to be so very hot that she doesn’t need a hassle with other predators either today.
Thank you to the Sea Eagle Cam, Birdlife Australia, and the Discovery Center for the camera that supplied the scaps of Daisy and her nest.
