Which animal is eating my fruit?

[Malhar]

Some animal has been eating my mandarins.  They eat it very cleanly and just leave he bark.  I am guessing rats but would like to get opinion from experts.

Think it might be fruit bats?

Not an expert but I have similar issue. It's almost always rats in my case. I caught a few by placing cheap traps close to citrus trees/possible traversal path. That said, I have also seen squirrels sitting on the fence and eating mandarins etc.

I think it could be birds, they poke through and slowly eat all the fruit. I have the same thing here. Rats or mouse like to harvest the fruit and hide to eat them. Not squirrels, they steal them and run away. So birds could do it, some aggressive birds. The thinner the skin, the faster they eat. They never touch my grapefruits, nor lemons.

Rats.

I have the same problem. When I go at night sometimes to check the backyard I could see the tree rats running and jumping in my mandarin tree. The more fruit trees you have the more critters come to enjoy your fruits.

Have not seen any birds or squirrells poking into the mandarin. That is why I doubt that they are the culpirts. What I find amazing is that animal eats mandarin pulp so tactfull that only the sheel is left without any traces of pulp.
