Yes, Nandina berries.

This is a popular ornamental shrub used by homeowers and professional landscapers, but the berries contain lethal doses of cyanide. Ornithological and conservation societies are urging people to stop planting Nandina because birds eat the berries and die within minutes. It’s quite a terrible death, too.

When dozens of Cedar Waxwings were found dead in Thomas County, Georgia, researchers at the College of Veterinary Medicine, University of Georgia, found the cause to be Nandina berries. All the birds had intact Nandina berries in their crops. There was hemorrhaging in the heart, lungs, trachea, abdominal cavity and other organs.

Further to the point, here is a slideshow on foods that people commonly eat and which should not be given to birds, or should be prepared (such as by removing seeds) to be made safe for them. Not everything in the slideshow is a fruit (e.g., caffeine, chocolate), but it does include de-seeding pears, cherries, avocadoes, and apples. The fruit pulp is OK but the seeds are toxic.
