Cool... Do the hummers pierce the skin of the grapes as in that first photo or do they wait for overly ripe ones?

Thanks for the shots, they're great. I never knew they would go for grapes.

I could be wrong but Im guessing they are going after the critters the overripe grapes might attract such as fruit flies and other small insects.

Honestly, I am not certain. I do think they are going after the grapes, but it sure could be the critters. I don't know for sure if they pierce the skin or not because I have so many others after the grapes (orioles, finches, grosbeaks, they all love the grapes), that I could not say for sure whether the hummers pierce them or only go after ones the others have already penetrated.

Now you all have me on a mission to figure it out. Unfortunately it will be next spring before I see these guys again.

Interesting for sure. I bet they do try for some of that sweet grape juice.

There was a nectar feeder on that same pole that the grapes were on but they often went for the grapes rather than the nectar.

I had to laugh this summer. I've been making a serious effort to buy and use only home-grown or locally grown food, or at the very least, grown in the US. But I had to buy grapes from Mexico and oranges from South Africa for the birds, LOL.
