Yew berries. They're not actually berries but arils. I first learned about them a few years ago when I noticed a flock of bird twittering in a yew hedge. They stripped the tree within an hour, gorging on the berries. I just finished taking a class with master teacher Priscilla Long. I was working on an essay on foraging and one of my fellow writers was writing about a patch of dirt in her yard that is next to a yew tree. She mentioned the "poisonous looking" berries on the tree. I told her they were not--I think it's just the fluorescent pink and the gelatinous texture that makes people think they're poisonous.
Then I got a couple of books on edible plants from the library and learned the seeds (there are hard brown seeds inside those bright pink fruits) are quite poisonous. I was so relieved to see Chris in class the next week and hastened to let her know she should not eat the berries. Apparently birds can eat them because they don't digest the seeds but simply poop them out, thus helping the yew to reproduce.
The yew's reputation for toxicity is well-deserved. Both bark and leaves are poisonous.
