Graphic with two parts, a map and a chart. Top section: A map showing intact tropical forests in northern South America, most of them in the Amazon River basin. Three locations are called out: 1 is in Panama; 2 is on the eastern border of Ecuador, near the borders with Colombia and Peru; and 3 is in Brazil, on the Amazon River. Undisturbed tropical forest areas are defined as areas where no disturbances were detected in a comparison of satellite imagery from 1990 to 2024. Bottom section: Dot plot with confidence intervals. For each of the three map locations, the chart shows the average annual change in mist net captures for insectivores and for the total bird community. For all three locations, the average annual change for insectivores is in the negative and is lower than for the total bird community.

Intact tropical forests are seeing mysterious bird declines. Is another “silent spring” brewing?

In the early 1980’s, we began preparing separate spread wings to help illustrate features of birds that had never been accurately drawn.

Today our collection of spread wings is the largest in the world, preserving more than 40,000 specimens.

North American bird declines are driven by reductions in common species Declines in North American birds are driven not by rare species vanishing but by sharp losses among formerly common species.

🚨 First PhD chapter is out! My work thus far, with @andy2dobson.bsky.social

We found that formerly common species have declined the fastest, on average.

A new time tree of birds reveals the interplay between dispersal, geographic range size, and diversification Flight may affect the dispersal and evolution of birds. Using a new evolutionary tree, Claramunt et al. find that efficient fliers have broader geographic ranges, and speciation reduces range size, bu...

Not to state the obvious, but some birds fly better than others. The ones that are awesome at flying -- this means they can get around obstacles, right? Expand their ranges as needed? Maybe be a little less vulnerable to extinction?

Turns out it's SUPER complicated.

Hidden white and black feather layers enhance plumage coloration in tanagers and other songbirds Colorful songbirds use hidden white or black feather layers to enhance plumage color, an optical trick well known to artists.

Secondary Sympatry as a Sorting Process Early explanations for the frequent observation of exaggerated trait divergence in sympatric versus allopatric taxa focused on secondary contact between allopatrically speciating lineages and emphasi...

New paper out in Ecology Letters (open access): I and Daniel Matute consider 'species sorting' -- a bias in the outcome of secondary contact following the allopatric stage of speciation -- as a reason for the much-observed pattern of elevated trait differences in sympatric close relatives

Island size shapes genomic diversity in a great speciator (Aves: Zosterops) | Biology Letters Islands have long represented natural laboratories for studying many aspects of ecology and evolutionary biology, from speciation to community assembly. One aspect that has been well documented is the...

My first paper as a member of the Manthey lab is out in Biology Letters! We used whole genome data from a classic "great speciator" (the Solomon Island White-eyes) to explore the relationship between island size and genetic diversity.

this is how I learned there are two, completely unrelated Vanity Fair magazines lol

not Vanity Fair 😂

1. Today the NIH director issued a new directive slashing overhead rates to 15%.

I want to provide some context on what that means and why it matters.
