Hello Everyone,

Well, after three irritating days, the end of the ads is nigh. Thank you again to everyone who helped me spot those pop-up ads. WordPress assures me there should not be any, but…

At 1900, 38 Canada Geese flew over the conservatory in a line, not a wedge or V. Normally, geese fly in a V or wedge to conserve energy. When the leader gets tired, s/he falls back, and the next one takes its place. Being the leader is hard work; they are breaking the wind – creating a slipstream – for the other geese so that they can fly without expending so much energy. As they flap their wings, each bird helps to create a ‘lift’ for all the other geese in their formation. Research shows that flying in this type of formation also allows the group to communicate better. Talk about teamwork and cooperation. Humans have something to learn from our honkers.

Those V formations are quite extraordinary. You can’t tell from the ground, but the lead goose is the lowest of the bunch. Each goose behind is slightly higher than the one in front of it, all the way to the last goose, which is flying the highest. They do this because of the aerodynamics of their wings. The only goose that is using all its wing power is the lead goose… the point-man, so to speak. When that goose flaps its wings, it causes a certain turbulence of the air that’s following the wing. The next goose in line benefits from this swirling air, and doesn’t need to apply 100% of its wingpower. The next goose, again benefits from that one, and so on down the line. Flying in formation this way adds 71% more distance that they can fly than when flying alone!

So who gets chosen to be point-man? You’d think the one with the map! Or the leader? Or the new-guy? No. None of these. They actually take turns. When one gets tired, he will drop back so he can rest a bit and benefit from another goose’s turbulence. When migrating in good weather with favorable winds these guys can make up to 1,500 miles in a single day! That’s crazy, man! Hard to imagine, but it’s been done. They are migration masters.

So the flying at night thing … I’ve already touched upon one of the reasons they prefer the night. It has to do with that turbulence I just mentioned. You see, many other large birds (and these are large birds!) use thermals to gain altitude and to soar on. Raptors do this. Hawks, eagles, etc. During the day, the landscape is riddled with all kinds of thermals rising from the ground, all depending on what the surface looks like below; how much heat was absorbed and stored from the sun; if it’s dark or light … or even water. These thermals are great for raptors! Lots of vertical air movement all over. But geese don’t soar, and they don’t have need to fly in circles. They have somewhere to go. And all those daytime thermals are a pain in the butt; they don’t make for smooth sailing. Plus, they interfere with the aforementioned wing turbulence that they use to keep from tiring. At night, several hours after sunset, the Earth cools and those pesky vertical thermals disperse.

So that’s one reason they like the night. Another reason for night flight is to prevent over-heating (makes sense, right?) Nights are cooler, so birds that expend a lot of energy with constant flapping (as opposed to soaring) take advantage of the cool of the night.

A third reason is also something I’ve already mentioned. Hawks! And eagles! And falcons! All those guys are diurnal hunters, meaning they hunt during the day. Which goose in its right mind would want to share the not-so-friendly skies with something called a “raptor”? Now, if you’ve ever seen flocks of geese on the ground and tried to get among them or feed them or something, you may already know how mean and nasty they can get. People have used geese instead of watch-dogs. They are tough! Especially on the ground. But falcons, hawks, and eagles, hitting them from the air often spells doom. In other words, their goose is cooked. During the day, they often rest and feed and rejuvenate in the water where they are safe from raptor attack. As long as they stay in the water.

So given the choice, they take the red-eye.

Why Do Canadian Geese Fly At Night?, Forbes Magazine, 1 March 2018 (updated).

So why were the geese flying in a straight line over my house? I can’t find an answer. Maybe you know. Perhaps they were readying to land at Fort Whyte or at the river a few blocks away???

The other day Calico and Baby Hope watched ‘The Boyfriend’ as he ate at the feeder. I wonder what Calico was thinking. This was her little friend when she lived in the wild. They would come and eat together, but he always let her eat first. They would often rest under the lilac bushes. He will not come into the house; he runs away. I have tried frequently to get him to soften to me. So we make sure his food is out by 0900 and, again, at 1700. He also comes at other times, including in the middle of the night. Another animal, a raccoon, comes at night, eating everything still available and dumping the water from the bird baths. That means we must ‘jump’ in the morning to prepare everything for The Boyfriend’s arrival.

Dr Erick Greene and others around Missoula are keeping a close eye on Iris, Finnegan, Sum-eh, and Antali. It appears that all four are still fishing in the Clarke-Fork River. As far as I am aware, this is the latest that Iris has ever remained in the area. Her usual date for departure is 8 September. She must relish being a mum again to two such fine fledglings and having a mate like Finnegan.

Iris came to the nest at 0838 without fish. I did not see a delivery at the nest by 1100 on Sunday despite Antali’s persistent calling.

This person had a first hand view of Iris and family — have a read!

From Dr Greene:

Iris was at the nest at 0738 Monday morning. She was calling loud and seemed to have a piece of fish in her talons (??). She is looking for Antali and he did not come. She waited three minutes and when Antali did not arrive, she flew off towards the river.

At Charlo, is C16 catching its fish? Our fledgling observes the water below the nest and has returned wet, once, perhaps, with a fish. This is one gorgeous fledgling! That full crop sure makes me think he had an excellent breakfast.

C16 is always watching that water – unless he is sleeping! Can’t see those stunning eyes.

When I checked on the nest of Junebug at Dunrovin Ranch – which was several times including re-wind – I did not see anyone. Did you?

Just look at the fish that Beaumont delivered at the Newfoundland Snow Lane nest. Good gracious. There is enough for both of the fledglings. Will the winner share?

Still eating three hours later!

Niagara Bee Dad still delivering!

River was at the Sandpoint nest, but I saw no fish deliveries from Keke. Perhaps Keke is feeding River off the nest. River has been seen ‘wet’, and he flies back and forth to the river. Is s/he catching their fish dinner?

At the Golden Gate Audubon nest in SF Bay, Tully was last seen on the 14th of September.

Here is the video of the fly off: https://youtu.be/9MJdNDRKcEM?

Some more great information from the Dyfi Osprey Project in Wales, home to Idris and Telyn.

Hartley and Monty continue to bond – and then bond again – at the San Jose City Hall scrape. Love is in the air. https://youtu.be/pjskOK2DcNc?

Xavier. What can we say? Isn’t he the cutest little Peregrine Falcon? He always wants time to incubate his eggs, but…Diamond often has different ideas. They have been together for nine years. Today, he demanded squatter’s rights on those eggs!!!!!! https://youtu.be/fygxtkCjkwA?

Beautiful Sea Eaglets.

‘A’ remarks: “Both chicks did well out of that breakfast, and afterwards, they settled down together, side by side, to rest their giant crops (especially SE34!) and do a bit of preening. They are very companionable, the best of nest mates, and even when food is around, they have been behaving beautifully. Observing the pecking order seems to ensure peace at meal times – Lady is aware of the need to feed SE33 first if both chicks are at the table, although SE34 is now confident enough to accept food before its sibling has eaten if their relative positions create this situation. They are pretty much equal in size now and SE34 is confident and able to get himself fed. He moves forward if he needs to get closer to mum’s beak and he is not showing any behaviour that suggests that he feels intimidated at meal times. So all is going swimmingly at WBSE. “

And more from the morning of the 16th from ‘A’: “Lady was up early this morning (05:29). She found a substantial piece of feathered prey on the nest, so started feeding the littles, who roused themselves and got to the table despite the fact that it was still dark. Lady started by feeding a bite to SE33, as per pecking order, while SE34 found which direction the table was in (he had his back to it and turned around very clumsily, inconveniencing SE33 in the process). Once both eaglets were settled in their places, breakfast proceeded peacefully, with both nestlings behaving beautifully. 

Oh, I adore these two. I love what good nest buddies they have become, sometimes even allopreening and nibbling gently at each other’s facial feathers. They are so cute. I love these few short weeks on the nest, being cared for by doting parents and having little to do other than eat, sleep, grow and play. Their lives will be very hard, and their chances of successfully managing as juvenile sea eagles are not great based on previous years. Although of course they don’t realise it yet, these peaceful days in the nursery, as it were, probably represent some of the happiest of their lives. It is lovely to share them. “

I love storks. Even if you can’t speak German, you can enjoy the amazing images in this documentary. Click on the link above the image or copy and paste into your browser.

There is news from Portugal. I have signed up, but this file is thanks to UK Osprey Information and Jeff Kear, who kindly attached a translated version. Please scroll down and see the map showing where the ospreys have their spring and summer breeding grounds and travel to Portugal for the winter.

Real Saunders Photography has posted some images of M15 and F23. There is action at the SW Florida Bald Eagle nest. The streaming cameras are to be operational on 1 October. https://youtu.be/3wJeooaW6oI?

‘A’ comments on the Royal Cam chick: “At Taiaroa Head, both TF and TFT are still there, though TFT in particular has been moving around a lot, going down the hill and perhaps seeking out a suitable spot from which to fledge. He may just be exploring – he’s always done a lot of that. No parents came in today, as far as I am aware, but of course the chicks will be emptying their stomachs before their big take-off. (That doesn’t make sense to me – surely they would want to keep any remaining nutrients they were given by their parents, as they have never done any fishing of their own and the next meal they get once they do fledge may be some time away – I have no idea how they understand where and how to find their own food, having never been taught how to do so nor even witnessed the adults doing it. So to leave home with an empty stomach seems to me a risky thing to do. I suppose getting and staying airborne is the most important thing, and that, too, they will be doing for the first time. It’s an awful lot of difficult things to be doing for the first time when their survival depends on getting it all right on the first try essentially. The thought of it worries me terribly.”

I caught a feeding. How wonderful!

‘A’ also checks on the falcons incubating on the ledge of 367 Collins Street in the CBD of Melbourne: “At Collins Street, Mum left the eggs just before 11:17 for a morning break, but she is back quickly, at 11:18, and repositions herself on the eggs. Dad flies up to the middle of the ledge, chupping as he arrives, soon after 12:47. He has not brought food, though he may have stashed some for her somewhere nearby. He’s such a cutie and so chatty. F24 chats back as she gets up from the eggs, so hopefully, he is telling her where he has left her breakfast. But no. He dives off the ledge, which she watches with some shock it seems, gazing after him for a while before settling back onto the eggs. I’m still not sure about food deliveries at this scrape, tbough mum does not appear to be starving so there must be some (or, more likely, she is eating off camera from a stash spot where dad is depositing food). 

Dad is back at 14:46 to relieve mum, who flies off the ledge. Again  though, he brings no food. He doesn’t settle down to incubate, instead flying off the ledge at 14:46:30. The eggs lie uncovered in the mid-afternoon. sunlight.”

Calico’s got two Tips for the Day: Help Stop Bird Strike and if you find a bird that has hit a window, helpful tips on how to help them.

Migration is a time for bird strike, sadly. Calico wants everyone to protect the birds from breaking their necks on windows. The most economical way to do this is by using window paints available where crayons, markers, etc. are sold. We found the white worked the best. Just scribble. After migration season, you can easily clean the window paint with white vinegar. We purchased Feather Friendly dot strips. The company says they last ten years. Calico wonders about that but they have been very effective in preventing any birds hitting our conservatory or the windows in the sitting room.

Calico asks that you read this helpful advice:

The Geese that have been breeding in northern Canada and in Winnipeg are starting to migrate. They face many challenges but the other one is BREAD. Do not feed waterfowl bread!!!!!!! It causes ducks to get ‘Angel Wing’ and that also impacts Geese. If you see others feeding ducks and geese bread, be kind, but educate them. There is nothing more fun for children than feeding bread to ducks and geese, but that is not what they should be eating! It will kill them in the end. So, please help my beloved geese. Thanks, ‘PB’ for this article. It is so timrely.

If you have the time, please check out Amy Tan’s talk on line about backyard birds. I have so enjoyed her book and her journey to learning about the feathered friends that visit her garden and her creation of special areas for them.

Thank you so much for being with us today. Have a fantastic week! See you soon.
