Is there a website to compare local birdlists for each country?

I'm traveling abroad for the first time since getting into birding. I'm wondering, is there any tool online that easily can show you the differences in birdlife? Any kind of global bird info, where you can quickly see each country list? Maybe even filtered by season?

Or more concretely: I'm familiar with the birdlife in Germany and will travel to Sweden soon. Do I really need to manually check for the differences?
