For these birds, climate change spells a rise in fatal conflicts
Science Daily ^ | January 10, 2019 | by Cell Press

Researchers have found yet another way in which climate change has been detrimental to migrating birds. As European winters have become warmer, pied flycatchers traveling from Africa to reach breeding grounds in the Netherlands are arriving to find that resident great tits have already claimed nesting sites for the season. As a result, the number of flycatchers killed in great tit nests has risen dramatically.

"When pied flycatchers and great tits are more synchronous in their timing, this leads to a higher level of conflict over nesting sites," says Jelmer Samplonius, who did the work at the University of Groningen, the Netherlands, and is now at the University of Edinburgh, UK.

Samplonius's team got interested in the dynamics between pied flycatchers and great tits in part because both species rely on a short burst of food resources -- caterpillars -- to raise their young. When the birds' timing is well matched with the caterpillar peak, they are more successful in raising their offspring.

Given the reliance on the same food and nesting resources, it was clear the two species interacted quite a bit. Pied flycatchers were known for trying to take over great tit nests. They also eavesdropped on resident great tits to gain information the long-distance migrants otherwise lack about local conditions.

After years of careful monitoring, Samplonius says, "it was hard not to notice" that many flycatchers were dying in great tit nests. In other years, "virtually none" met that same fate.

They apparently come in various sizes...

And it appears they do not travel...

From the way global warming alarmists talk, you would think that the earth had NEVER been warmer.

Well, I'm sure that, if you ran the phrase "great tits" through ANY search engine, you would find a multitude of pictures depicting not only "great tits" but "exceptional tits", "phenomenal tits", etc ....

"If you look around for statistics about bird deaths from wind turbines get you wildly different numbers. Some say just 10,000 birds a year meet their end at the hands (blades) of the wind industry. Others ramp that number up to 600,000. Now, a new study tried to actually use science to estimate.

Of course, they didn't go to each turbine and count how many little feathered bodies they found at the base. Instead, they combed the literature for all the studies they could find on bird deaths, and tried to combine them into an estimate. This meant searching for fun things like “'bird AND wind turbine' with 'collision,' 'mortality,'fatality,' 'carcass,' and 'post-construction.'" And then—even more cheerful—searching all those terms again, but "with 'bird' replaced by 'avian' and 'wildlife'; and 'turbine' replaced by 'farm,' 'facility' and 'energy.'"

In the end, using 58 mortality estimates that met their criteria, they came up with an estimate. According to the current literature somewhere between 140,000 and 328,000 birds die each year from collisions with wind turbines."

I got pied and saw great tits but they weren’t in the
nest the next morning.

“They apparently come in various sizes...”

Do they gather in groups? Pairs, perhaps?

My understanding, based on some experience, is that they mate for life and are almost always found as secretive, constant companions - often hidden away from sight in a type of "double nest."

More research is required.

I'm doing my part, with real passion, but I am only one scientist...

Please volunteer, while there is still time to uncover these secrets.

But are they "real"?
Paging Gamecock for Seinfeld ping... d;^)

And ping for the "great tits" responses.
