Saturday 20th of April. It was rather hot on the Lizard Path. This male green-barred woodpecker, certainly muddled about the seasons of the year, was making a hole in a <em>Melia azedarach</em>, like those for breeding. He was seen working and the recently built cavity

On the Viamonte Canal very near the hut I found these two screech-owls in a
Sapiun haematospermum. Luckily foliage was not dense and they could be seen fairly well. They seemed to be asleep, but it was enough to get near that they opened one eye to see what was happening. If something did call their attention, they opened both. It seemed they took turns for surveillance. While one remained with the eyes shut the other spied with one eye half way open. One of them even leant on the branch to be comfortable. They did not move. Only the wind made them totter. Lots of photos for everybody even with cell phones of those who passed by. Do not miss the details of the eyes.

Tigrisoma lineatum

An impressive frog caught by the tiger-heron. So huge that if was believed to be an American bullfrog Lithobates catesbeianus, a bad omen if it had been. This exotic frog is a voracious predator which can eliminate or drastically decrease the numbre of native species when it settles in a new environment. Luckily it turned out a Creole frog which has grown bigger than normal
