Our mulberry tree

We have a big white mulberry tree at the backyard. I am not sure how old it is but it has been there since we bought the house last 1997. It never failed to give us fruits every year since we moved here but we've never used the fruits. However, lot of birds come to visit the tree when its in season including some fruit bats at night time. Most of its fruits just drop off and claimed by the ground. When my kids used to raise silkworms, we didn't have trouble looking for food. The silkworms can eat as many leaves as they could stomach as the tree has plenty of leaves that can even feed a whole army of silkworm.
I like the tree in summer time for it gives shade in our backyard that even during hot days we can still stay outside under its shade while on Autumn time the leaves turn to yellow and drop off to the ground. I don't mind cleaning up my yard with thousands of mulberry leaves. I just use a blower vacuum to suck and at the same time munch the leaves ready for composting. That way, it saves my pocket from buying fertilizer. Although it takes time to compost them but it's worth the wait.
Here are some of its frequent visitors but I am not exactly sure what birds they are.
