While in Salta I got an invitation to join a group of friends on a fishing trip near a place called Goya, in the mighty Paraná River, the same river where we have spent some great days fishing in the eighties (See: https://bushsnob.com/2015/01/28/a-fishing-expedition/).
This time the fishing was not memorable as there seems that the river is suffering from too much fishing pressure and the large fish are disappearing.
At one stage during the fishing we were traversing a smaller tributary known as the Santa Lucía River when I spotted three large birds of prey circling a floating object. I kept watching their activity from about one hundred metres away and saw that one of them landed in the water and started to peck the object.
I realised that the birds were three Caranchos or Caracara (Caracara plancus) and I was surprised to see one landing in the water. Then, the bird lifted the object in its paws and started to fly away but dropped it. At that time, I saw that what they were mobbing was a smaller bird so we went to have a look.
While moving towards the spot, there was a second attempt at lifting the bird again and, again it was dropped.
Our approach scared the predators and we found the prey to be a Ringed Kingfisher (Megaceryle torquata), a rather unusual target for the Caracaras that, although known as opportunistic, I did not think capable of going for a rather large kingfisher!
When we approached the bird, it swam with the aid of its wings towards us.
I lifted the bird, risking its rather strong beak. Soon I managed to close it with a sticking plaster to avoid becoming a victim myself! I checked the bird and, fortunately, it did not show any visible injuries.
I kept the bird on the boat for about two hours, waiting for it to dry and to keep it from struggling I covered it with my hat, burning my bald head in the process!
Eventually, it got dry and became rather active so I judged that it was as ready for release. As soon as I removed the plaster and held it in my hand for a few seconds, it flew away strongly.
Unfortunately I can only speculate as to how the kingfisher ended in such a tight spot that, surely, would have cost it its life if we would not have come to look. In my view, the most probable scenario is that it was a young and inexperienced bird that had recently left the nest and, being still insecure, made a mistake spotted by the caracaras that took advantage of the situation. However, I could well be wrong.
