I did a search on this as I have not heard any problem with it and it is an extremely common thing that people feed to birds. I had a hard time finding anything that claimed it was as dangerous as that, but I found some things that said it's somewhat of a myth. Here is just one:

3. Is peanut butter bad for birds? Will it stick to the roof of their beaks?

This topic is hotly debated, but there is no scientific evidence one way or the other. We humans sometimes have trouble digesting large mouthfuls of peanut butter, so is it logical that the same is true for birds? Not really. Birds' bills do not have as much saliva as human mouths, so it is less likely that the peanut butter will get gooey and stuck to the roof. To be safe, it's smart to mix chunky peanut butter with whole oats, raisins, cornmeal, and other ingredients to make it drier and more solid, and thus less sticky when it enters a bird's bill. Offer only small amounts and offer a source of water, just in case a bird wants to get a beak-cleaning drink.

I truly do not think using peanut butter with seeds is that large of a danger. I did read over many many links to make sure though so I don't feel uneasy about it
