Kiskunsag again

I went to the Kiskunsag again for a day, this time guiding a keen birder from San Diego in Southern California. It was interesting to compare the sightings from two consecutive days. More or less the same number of species, the 2 Rollers we saw in the same places as the day before, the Great Bustards more or less in the same spots but the Monday Red-footed Falcons half a mile away from the Sunday ones, and more of them! An addition yesterday was two White-tailed Eagles, one adult, later one immature. Another difference was that yesterday we really struggled to see Bearded Tits! Though they called and called, they would not show themselves... finally a male did, but it was hard work. Maybe because this was one of the species that my guest really wanted to see? You know, Murphy's law and all that? Or is it some other kind of law?
