Passerines also called Songbirds account for more than half the earth’s birds population.
At this time, nearly half of the birds disappeared the last 40 years.
Passerines species declined considerably
A great work of observation in Canada’s Boreal Forest pointed out that we’re losing common species, everywhere in the world. Since persistent decline over the last 40 years.
In France, The Skylark (Alauda arvensis) about more than a third has disappeared yet.
Based on 20 billion birds, about Half die every year during migration periods.
On their migratory routes, from the breeding area to an appropriate wintering area for millennia, now they have to face more dangers, as deforestation, a new and urban landscape
Many people are worried about the consequences, as in Utica, New York State, where team of volunteers look after birds, they are so small and are subject to predators by night.
Did you know?
The little ones may travel vast distances, up to 1000 kilometres in a night! so Impressive.
Causes of birds mortality
Regarding predators, it has been clearly reported that Cat predation caused 32 species vanishing. Uh!
In USA, a study pointed out also that the growing numbers of cats has increased a lot, as 80 million domestic cats, about 30 to 40 million abandoned cats… also reported that about 1.4 billion migratory birds died due to cat predation in Usa/Canada, in some parts of Europe as well. Incredible? but True!
But of course, and once more, Humans are mostly responsible, well, we are the crux of the problem…
Another major cause of birds mortality is about hunters. Indeed, In France, they killed between 500 000 and 1 million every year.
Sparrows, Larks, The Ortolan Bunting “Emberiza hortulana”, an endangered species traditionally, but illegally hunted in France. Nowadays, hunters barely get ONE Ortolon during the hunting season, since they also contributed to their vanishing.
More obstacles during migration
The landscapes they used to fly over have seriously been modified.
Many buildings with glass facades cause the death of several thousands migratory birds In Canada, Too many birds died due to huge frontal glass facades. In Canada, Scientists monitor 167 bird species populations, which 20 are endangered bird species.
Light pollution is very harmful to birds of which two-thirds fly at night, and constitutes a serious threat to migratory birds.
Fortunately, many people Rescue, Help and ensure that migratory birds are maintained, protected, and conserved.
Thanks also to Birdcast program, ebird organizations that Record the birds we see, Keep track of bird lists, Explore dynamic maps and graphs,
Share sightings, join eBird community, Contribute to science and conservation.
Also thanks to Max Planck Institute for Ornithology with ICARUS; “International Cooperation for animal Research Using Space”, is a global collaboration of animal scientists to establish a satellite based infrastructure for earth observation of small objects such as migratory birds, bats, or sea turtles…
Just a friendly reminder : in little more than 40 years, too many birds have disappeared, around half the world’s population.
and as also commented by André Solaner wordpress.com🙂 : “It’s not only the birds. Over the last 25 years the amount of insects in Europe decreased by 75%. Only about a quarter of the insects is around compared to the amount 25 years ago. What a drama 🙁 “
We all have to take urgent action before we reach the “point of no return”.

because, before …
will Birdsongs soon be no more than a memory?
Thus one wonders “who” is next on list?
My conclusion is this:
It is about a falling…on the way down everybody keeps telling to reassure himself:
“So far, So Good…” … “So far, So Good”… “So far, So Good”… since, How we fail does not matter… it is how we land! (j’me comprends!)
Last, Hats Off to all ornithologists, witnesses, enthusiasts, researchers, observers, teams of volunteers everywhere in the world!
That’s All for now.
“So far, So Good…”
Thank you for reading. Enjoy a Perfect day…
