Subject: mulberries
I have been corresponding with Kannan on this, but others might be interested in the fact that mulberries are primarily water and offer little nutrition to birds:
Water: 85-88%
Carbohydrate (sugars, mainly glucose and fructose, producing the sweet taste): 7.8-9.2%
Protein: 0.4-1.5%
Fat (mainly fatty acids, such as linoleic, stearic, and oleic acids in the seeds): 0.4-0.5%
Free acids (mainly malic acid, producing the sour taste): 1.1-1.9%
Fiber: 0.9-1.4%
Minerals: 0.7-0.9%

Ted Stiles did the pioneering work on this back in the 1980s In his 1980 American Naturalist paper, he points out that mulberries are the first tree to fruit in the Eastern deciduous forest and, as such, they do not have to provide a high reward fruit to attract birds and mammals because there is nothing else in fruit. So they produce a massive amount of low-quality fruits that are mostly water...

Cheers, Kim
