Nice study on the importance of parental care on ontogeny of behavior. Just like in e.g. chimps, golden-winged warblers develop adult-like foraging behaviors while still being provided for. onlinelibrary.wiley.com/doi/epdf/10.... #generalprocess #birds

E.g. so called What-Where-When memory ≠ episodic memory. Other animals are expert discriminators (what), excellent at spatial mnemonics (where) & can encode time with some kind of precision. Screenshot from our paper:

It's interesting to be part of the animal cognition field. "We" are acting like episodic memory in animals is a settled fact, even though it’s still debated. And then papers are written about its function as if everything is fine. Isn't this intellectually sloppy? #scientificslippage

Happy New Year! Here are some favorite photos of animals I saw this year. Two from Stockholm where I live, and two from Brazil where I spent the summer. #naturephotography #stockholm #brazil

For this reason, we wrote this comment, published yesterday. royalsocietypublishing.org/doi/10.1098/...
We reason that 1) their data supports rather than rejects the sequence hypothesis, as monkeys and chimps did not perform with any precision in these sequential tasks. 7/n

Few tests have been made of this hypothesis (that only humans can in general represent sequential information faithfully), and then a creative new study came out, with impressive sample sizes:

We also presented a model that successfully accounts for how non-human animals represent sequential information:
royalsocietypublishing.org/doi/10.1098/...
Importantly, this model better explains sequence discrimination experiments than do ideas from rule learning, artificial grammar, etc.

Oops, something fishy with the silver medal-winning photo of barn swallows, reward was removed last week. This photo from the competition Bird Photographer of the Year has disappeared from many sites, but has remained on this site (so far):

We got a reply on our Sequence Bottleneck-paper! Jacobs et al. argue that many observations go against our suggestion, see:
www.cell.com/trends/cogni...
Not surprisingly, I guess, we argue that their examples don't really cut to the chase. Our full response here:

Now in high impact journal, crows learn new behaviors through trial-and-error. Ignoring Skinner for now, let's reiterate Tinbergen in The Study of Instinct: Animals must learn to i) do new things, & to ii) refine existing behaviors. Our five cents on this: royalsocietypublishing.org/doi/10.1098/...

A bit late on this, but here we explore how cultural information
can guide development of behavior & cognitive skills just like genes. Can cultural evolution result in teaching trajectories that promote incremental acquisition of complex tasks?

There's a lot of hype in animal cognition today. In this @royalsocietypublishing.org paper we go back to basics & look at sequential aspects of animal intelligence. This makes evolutionary sense & has consequences for how we interpret animal behavior.

Ah, toppen! Kollade antal obsar i Uppsala kommun i maj- och juni på Artportalen (med alla begränsningar det innebär). Antalet obsar verkar inte ha ökat, men juni är så klart inte slut än.

Det går inget vidare för starar (eller för andra så kallade jordbruksmarksfåglar), de minskar stadigt. Här bra data från Svensk fågeltaxering: www.fageltaxering.lu.se/resultat/pop...
(Däremot är nu årstiden då ungarna nyss lämnat boet och far runt i flockar och märks väldigt mycket.)

12th ever ring-billed gull/ringnäbbad mås in Sweden. This one has been hanging out in central Stockholm for more than a week now (easiest to see in Kungsträdgården).

Ah, yes, forgot this one. "Crow statistical inference" does not seem to stand to scrutiny, either. A learning model accounts well for data, refuting Johnston et al.'s claims of crows calculating reward probabilities with some abstract magnitude representation. journals.sagepub.com/doi/abs/10.1...
