Canadian blue-spotted salamanders, from egg to adult


This November 2019 video from Canada is called Blue-spotted salamander: from egg to adult.

Canadian autumn migratory birds, trees video


This 2019 video from Canada says about itself:

One hour nature 4K footage compilation of North American autumn foliage and migratory birds. The fall is a prime time for bird migration as most species established up north for the summer head back down south for the winter.

Footage was filmed in the wild in 4K in Southern Quebec and Southern Ontario between September 29th to October 6th.

Species seen are:

Yellow Rumped Warbler
Blue-Headed Vireo
Brown Creeper
White-Breasted Nuthatch
Pileated Woodpecker

Canadian songbirds, new research


This 2018 video from Canada says about itself:

Ontario Backyard Songbirds – Bird Calls, Songs and Sounds

This video has some of my best footage of birds either singing or calling, and making sounds. There are a variety of birds that are found in my backyard, some stay for a while and sit in my yard and some grab some food and leave as quickly as they can.

This is a compilation of the many backyard birds chirping, singing, and calling.

Birds Included in This Video

Northern Cardinal
Common Grackle
Brown-headed Cowbird
Red-winged Blackbird
Black-capped Chickadee
Baltimore Oriole
Mourning Dove
American Robin
Blue Jay
American Goldfinch
House Sparrow

Understanding why songbirds choose their homes

December 19, 2019

New research by University of Alberta biologists uses a new approach to modelling the populations of six species of songbirds in Canada’s boreal forest — and the results show that standard modeling methods may not be accurately capturing species distribution patterns.

The study shows that birds of the same species do not necessarily use the same habitats in different parts of the boreal forest, a phenomenon they termed differential habitat selection. They developed habitat models to account for this process to give better estimates of population size and distribution.

“Knowing how species select habitats differently in different parts of their range is an important first step towards a better understanding of their ecology and how populations will respond to human disturbances and conservation efforts,” explained Andrew Crosby, postdoctoral fellow who works with Professor Erin Bayne in the Department of Biological Sciences.

The researchers examined nearly 20 years of population data following six boreal songbird species in the Canadian boreal forest, including the Blackburnian warbler, the Black-throated Green warbler, the Brown creeper, the Canada warbler, the Cape May warbler, and the Connecticut warbler. The results clearly show spatial variability in habitat selection within species.

“Bird populations may not respond to changing environmental conditions the way we expect them to if we assume that habitat selection is the same under all conditions and in all places,” said Crosby. “This means that the same management actions will likely have different effects in different places. Policies and management strategies will be much more effective if they are tailored specifically for different regions.”

The research provides a path forward for improving conservation planning and information for making informed policy decisions and resource allocation.

Donald Trump-Trudeau quarrel, parody song


This 4 December 2019 music video from Britain is a parody of the Beatles song Hey Jude.

It is about the quarrel of United States President Donald Trump with Canadian Prime Minister Justin Trudeau at the NATO summit in London.

The video says about itself:

The Tweetles – Hey Trude

Donald Trump’s Beatles tribute band has a musical message for Justin Trudeau.

LYRICS:

Hey Trude, don’t make it SAD!
Took a summit and made it bitter
Remember I don’t know the Duke of York
And your locker room talk
Has got me triggered

Hey Trude, don’t be two-faced
One looks so great, the other one I hate
Which one has been talking behind my back?
Must be the black
I bet it’s Kenyan

So let me out, I’m going home
Hey Trude, you blow
Keep your dirty hands off my Ivanka
And stay away from Melanie
Hey Trude, don’t be

Wa-wa-wa-wanker!
Wa-wa-wanker!

Hey Trude, don’t make me SAD!
Took a summit and made it bitter
Remember I don’t know the Duke of York
And your locker room talk
Has made me triggered
Triggered, triggered, triggered…
WAAAAHHHH!

TRUMP ONCE CALLED PRINCE ANDREW ‘A LOT OF FUN’ President Donald Trump can’t keep his story straight regarding his relationship with Prince Andrew. On Tuesday, he claimed that he didn’t know the disgraced royal. But People dug up a 2000 interview with Trump in which he’d said of the prince: “He’s not pretentious. He’s a lot of fun to be with.” [HuffPost]

Trump denounces Macron’s criticisms of NATO at London summit: here.

WORLD leaders gathered in Watford today as the Nato imperialist war machine attempted to paper over the cracks with growing rifts between the supposed allies. Much attention has focused on a perceived spat between French President Emmanuel Macron and his authoritarian Turkish counterpart Recep Tayyip Erdogan. Both are accused of war crimes — Mr Erdogan for his jihadist-backed ethnic cleansing campaign against Kurds in northern Syria and Mr Macron for the sale of arms used to deadly effect in Yemen: here.
