I'm fairly knowledgeable about New Jersey birds, but not at all about Czech ones. I imagine the arboretum had some beauties in it. Was that in CA or NY (or other place)? I know CA has oodles of wonderful birdies.

We do! All sorts of birds - although not Cardinals, which I've seen in Texas. The arboretum was just 13 miles from where I live.

Czech Republic has some attractive birds, but the ones I see near my house are all quite plain-looking. Plus, they piss us off that they refuse to eat the seed from our bird feeder. I tell my husband that they dislike it because it is too modern-looking (like a Frank Lloyd Wright house). Maybe they only go to places that look like European cottages . There are a few birds in CZ that I'm familiar with, but the doves make a slightly different cooing noise than the ones in New Jersey. Strange. Well, they speak a slightly different language here.

How strange that they don't eat your seed! Also, that the doves sound different. There must be different types of doves, maybe more than we know of.

We could only view part of the cemetery today because of covid closings. In any case, what we saw was amazing and it is in a beautiful, quiet hilly area. One of the oldest Jewish cemeteries, outside of Israel, is in Prague. It's a major "must see" for anyone, but particularly people of Jewish heritage (The Wikipedia entry on it is interesting: Old Jewish Cemetery, Prague - Wikipedia).
