THE TRUE REASON WHY AMERICAN ROBINS MIGRATE EARLIER!

A bunch of researchers from a bunch of US universities finds out that the timing of American robins' (Turdus migratorius) "spring migration to [their] Arctic-boreal breeding grounds" (P) got 12 days earlier in the last 20 years (about 5 days per decade in the 1998-2018 time period).

Moreover, the brains analyze data collected between 2016-2018 from GPS tracking devices stuck on the backs of 55 American robins. And these data indicate that "the [American robins'] arrival timing and likelihood of stopovers, and timing of arrival to breeding grounds" (P) are highly impacted by the environmental conditions the birds find along their migratory paths. Among the factors, the "dynamics in snow conditions" (P) appear to be a key one

The researchers' study (P) is published on the journal Environmental Research Letters and can contribute in creating predicting models of birds' responses to climate change.

The findings are coherent with what scientists already know, which is that one of the strongest effects of "global climate change has been the advancement of spring at high northern latitudes [...] where temperatures are rising nearly two to three times faster than the global average" (P), and that migratory birds adjust their trips' schedule to their breeding territories in response to the changes in local climate. 

But, dear reader, this dumb blog has an alternative explanation for the earlier migration's timing of American robins. And a cartoon to explain it.

É ARRIVATO IL NUOVO PODCAST IN ITALIANO: @sciencemug ITALIA!


Oooh bentrovato e bentrovata oh tu che ascolti/parli/pensi in italiano, qui su @sciencemug, il podcast/blog che racconta la scienza mentre contempla il dorso della tartaruga che regge l’elefante che regge il mondo che si gratta sguaiatamente l'Himalaya, eeee sente anche le voci del multiverso cantare il caos armonico del tutto e occasionalmente raccontare barzellette sconce con in sottofondo l’inconfondibile brusio del bar più malfamato della costellazione del Tucano.
 

Volevo informarti, caro auscultatore e cara auscultatrice, che ora potrai goderti ooogni contenuto di questo matto podcast anche in italiano.
 

“Perché?”, mi chiedi con un vago accenno di scettico sospetto? 

Beh, caro auscultatore e cara auscultatrice, perché adesso esiste anche @sciencemug ITALIA, dove potrai ascoltare tuuuti i nuovi episodi, e un po’ alla volta anche quelli vecchi, in italiano, appunto.
 

@sciencemug ITALIA è su iTunes, Spotify, Anchor, Castbox e presto sarà disponibile anche su altre piattaforme.
 

Benone, oh voi del quelli che il podcast sì ma solo in italiano, la notizia ve l’ho data, adesso vi saluto, che devo tornare a inseguire il bianconiglio.
Ciaz!

THE TRUTH ABOUT FLAMINGOS' SOCIAL LIFE!

Soo, dear reader, from 2013 to 2016 a bunch of scientists studies (P) flocks of captive flamingos at the WWT Slimbridge Wetland Centre, a center for science and conservation in the UK.

And the brains find out that the pink birds have pretty intense social lives, that the larger their flocks the more frequent their social behaviors, that "arrangements of dyads, trios and quartets with higher ties strengths were visible [with both] male-male and female-female [stable over time] bonds", and, ultimately, that "flamingo societies are complex (i.e. formed of long-standing preferential partnerships and not loose, random connections)" (P).

So, dear reader, for you and you only, this dumb blog, in the two following cartoons, respectively reports a truth that the good researchers failed to uncover (A), and a common example of what the intense social life those cool flamingos have looks like (B).

THE TRUE NATURE OF CATS-SPECIFIC MUSIC (THE ONE THAT LOWERS THE FELINES STRESS LEVEL)!

So, dear listener, a bunch of researchers do a study (P) on the effects of cat-specific music on the felines' stress level when the furry pets go to the veterinary.

And the scientists find that: "cat-specific music can significantly lower stress-related behaviors in cats visiting the veterinary clinic for wellness examinations. Adding cat-specific music to veterinary offices as environmental enrichment could provide great value to the cat’s welfare in the clinic" (P).

The cat-specific music the scientists refers to is "purring and suckling sounds [...] layered into tempos and frequencies used in feline vocalization music" (P)

But, dear reader, this dumb blog in the following cartoon is showing you the real nature of the "cat-specific music" the cats find so relaxing.
