The unripe fruits and the milky sap of several mulberry species are
mildly toxic, and can cause hallucinations and stomach upset.

I just had lunch with a friend who has two mulberry trees on his
property. This year, shortly after the fruits began to appear
(whitish-green when unripe, going to reddish-black when ripe), he
began to find dead birds under the trees: 5 Starlings, 2 male
Baltimore Orioles, 1 Gray Catbird so far. There is a strong
correlation (timewise) between fruiting and the deaths. Is anyone
familiar with this phenomenon?
