Hello, I'm concerned about a juvenile Eurasian Jay

Hello, I wondered if anyone knew if this was normal for Jay's tongue to look like; at least, I think it's the tongue... 

I've seen an adult Jay's tongue, or at least part of one before. I know the young ones don't go black in the mouth till they age, but this looks suspicious to me? 

For context, she has had some peanuts, as you can tell from the peanut skin. 

Should I be concerned about some kind of disease she may have? I'm concerned about it spreading as much as I'm concerned about her. 

Thanks.
