A retired Swedish couple visiting Yerevan for a wedding enjoyed the extended days and credit given by the airline. Also have insurance on their tickets, all in all not a bad deal.
A couple that takes bird watching seriously. Each partner has a binocular. Ara the driver has a good sight for spotting birds. Coming back from Garni we saw a small bird flying very low that took refuge under a rock. It was an owl. Checked the book and yes, this kind of owl exists in Armenia and is active in daylight. We (Ara and I) borrowed the binoculars and watched the owl; in turn, it was watching us. When we drove, the bird flew parallel to us. Today, coming back from Sissian Ara said they saw a man who had caught three live giant baby owls. Wonder how big they grow.
A drive in the country and even without binoculars you can see soaring eagles, falcons and bright blue-green breasted birds (probably bee-eaters). A drive in the city crows (really, who wants to see them), magpies, swallows, nightingales and crowned light-brown woodpeckers and much more.
Not a bad place for bird watchers.
