OK, I recently recommended Medlar Comfits, but I thought I'd mention a few other blogs and sites I've come across lately.
George Bristow's Secret Freezer is a bird watcher's site of great grace and interest. Martin Collinson, near Aberdeen, does history, morphology (beautiful plumage!) and all kinds of nice stuff. A bit like an old bookshop that does natural history.
Agricultural Biodiversity Weblog discusses the forgotten aspect of biodiversity - the crops and animals we rely upon, and their wild relatives.
The Ranger's Blog has interesting snippets about environmental and conservation issues in the UK (including a nice essay on the way to estimate the age of hedgerows).
Genetic Archeology reports on the use of modern forensic and genetic techniques as applied to archeology, and it has a bit of anthropology and primatology as well.
And Science Notes covers all kinds of interesting bits of news, such as the Guardian's portal on Homo floresiensis.
Thanks for this post, I always enjoy reading new perspectives, especially that of the Agricultural Biodiversity Weblog.
