Do birds have heart attacks?

Yesterday while on my way to my regular Saturday afternoon coffee with SU, suddenly from a corner of my eye I spotted a bird that was falling from the sky with high speed. For a moment I was afraid it was going to hit me, but fortunately it landed in a nearby stream. At first I thought the bird was fishing, but on closer inspection the animal was floating on the water and was dead as a stone. Which raises the question: do some birds die of sudden heart failure? I always thought animals felt they were getting weaker, and would either become prey for other animals or sit quietly in some hidden spot until it was their time to go.
In the evening I went to April and wow! everyone was there. It has been a while that so many friends and acquaintances were all there. Good to catch up with some of them and I was also introduced to some new people some of whom seem to be nice guys. I was happy when cycling home around 4am but missing someone very much at the same time - you know who you are.
Today OS' brother AF and his daughter PR (15) and son AFjr (8) arrived from Colombia. The trip is a Quinceanera birthday gift for PR. In Latin culture, the 15th birthday for a girl is her entrance into adulthood and a big celebration must be done. I could tell that PR is ready for adulthood when I walked into the living room (the rest of us were in the garden enjoying the nice evening) and PR had found a soft-porn channel on TV. The family will be here until July 19th. At least it gives me a chance to improve my Spanish as they only speak that language.
Watched part of the first set of the Roland Garros final Nadal - Federer while waiting for the guests at Schiphol Airport, and most of the 3rd and 4th set at home. Nadal was superior and I was glad he won. Firstly, he is much cuter than Federer, and secondly he is from Spain and Federer from Switzerland. I mean: who would support someone from a country of xenofobic money-launderers? Hehe
