Perhaps the most prolific area of wildlife we saw in Costa Rica was the Caño Negro National Wildlife Refuge, in the north of the country near the Nicaraguan border.
One of many highlights during our boat trip on the river was this large group of black necked stilts, apparently fairly common throughout the central Americas. Fairly obviously, the name comes from those long pink stilt-like legs and the black rear of the neck.
According to the RSPB, stilts are rarely seen in the UK, apart from avocets, which are of the same family but have an upward curved beak.
I may be paranoid, but along the river there were just small signs of creeping low level development – the odd landing stage, clearing, dwelling, fishermen – along the banks of this magnificent wildlife haven. For how long?
