My inbox is being flooded with fully AI-generated emails from prospective students. I tried to work out why I can't bring myself to read them, and ended up with some thoughts and advice for writing cold emails in the age of AI. My new post: blekhman.substack.com/p/why-i-am-n...

Environmental groups sue government to stop a big change to the Endangered Species Act
By altering the definition of the word "harm" as used by the Endangered Species Act, the Trump administration may limit how wildlife is protected in the United States. Environmental groups are suing.

Brought some #ornithology students to the north shore for sea duck viewing. What fun, although the harbor seals stole the show!

The data is in: the NIH goalposts have shifted. What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards. Another manifestation of how HHS policies have led to fewer awards and less science.
Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

Teaching ornithology this semester to mostly pre-health students, and it's probably my favorite class to teach. It's nice to review some of the recent literature, and here I'll post the papers that we discuss in class.

Took my ornithology class on a bird walk for the first time yesterday. It's so great to see reactions of awe and joy when somebody looks at a bird through binoculars for the first time. Thanks to the trio of black-capped chickadees who hung out by us for a bit! ebird.org/species/bkcchi
ebird.org
Black-capped Chickadee - eBird
This tiny, plump-bodied, big-headed bird is a familiar woodland resident and backyard visitor in the northern U.S. and Canada. Gray overall with light buffy flanks and a contrasting head pattern: black cap, white cheek, and black throat. Short, stubby bill is used for hammering open seeds. Often the core of mixed flocks of songbirds. Visits feeders. Nearly identical to Carolina Chickadee, but range barely overlaps. Especially note voice, brighter white on wings, and buffier flanks on Black-capped. Beware that hybrids occur frequently in the overlap zone and some are best left unidentified.

sad news - Duke University decided to dump their herbarium, which has over 800,000 plant specimens, one of the largest among in America, and includes many type specimens of Lady Gaga ferns. What a shame. Please stop Duke admins for making this horrible mistake!!
