I don’t have an opinion on Maeve’s gull, but I do have some resources for beginning and advancing gull-watchers. My "Getting Gulls” lecture is now posted to my Chasing Nature <https://chasingnature.substack.com/> site (on Substack). This is a new version of the lecture I used to give in person years ago.
Although my essays about wildlife, wild places, and the human condition are free at Chasing Nature, the gull lecture and other instructional resources are there for readers who support my work with a paid subscription. (My “Practical Nature Photography” seminar is there as well, for example.)
I’d like to offer these lectures gratis, but Chasing Nature is now how I earn a living. Again, except for some eco-resources behind a paywall, most everything there is free (just yesterday, for example, I posted an essay <https://chasingnature.substack.com/p/snowy-owls-in-decline> relating to a new review paper about Snowy Owls in decline). If the $5 monthly or $50 annual subscription fee is a burden, send me an email — we’ll work it out.
By the way, for those of you who don’t know Substack, it is an online platform for independent writers (lots of us) and millions of readers. I read a ton there: Bill McKibben, Heather Cox Richardson, and other brilliant minds you’ve never heard of, including voices of sanity from the natural world and from culture and politics.
Lots of birders write on Substack. So whether you visit Chasing Nature or not, I encourage you to check out the platform. (Then again … you know … I’m biased and in the tank for Substack.)
