When I saw the jacana fighting, I first thought it was taking care of the chicks, but when I zoomed the image I realized there were eggs. First some Rose-billed Pochard juveniles came near and then a coot. The jacana got very nervous because the coot was getting too close. When all visitors moved away, the jacana calmed down, checked the eggs and settled to heat them

On December 11th for the first time we saw the four newborn jacanas. They folow the father and feed themselves. As they are so little the father keeps them warm by hugging them with his wings. The little jacanas position between his body and his wings, so the father must crouching so that they may take position. Since they are short, their legs dangle. The heat session lasts about 2 minutes and repeated the operation three times while we were there. We tried to discover the signal to gather the chicks, but we could not. No sound was heard. Only the head movements, sort of hiccups were seen. In the video only three chicks appeared but all four were there.
