The Portea Leptantha, an endangered bromeliad

A unique world in a bromeliad

Bromeliads are plants which grow exclusively in the tropic and subtropical Americas (Neotropics). Most of these wonderful and colorful plants come from the Atlantic forest in Brazil.

Bromeliads are found at altitudes ranging from sea level to over 14,000 feet. A wide variety of bromeliads can be found in Brazil in different habitats from the hot, dry semi-arid regions of the caatinga, the moist rain forests along the coast and up in the cool mountainous regions.

They can be observed in a variety of growing situations: Some Terrestrial species are found growing in the ground like most plants. Saxicolous species grow in small sections of rocky soil, large rocky surfaces and hanging on cliffs as well, where their roots may penetrate cracks and fissures to locate moisture or organic nutrients. However they can do well if placed in large branches of a tree by human interference. Epiphytic species are found growing on other plants, usually trees or shrubs. They are able to take their nutrition and moisture from the atmosphere and are for that reason called "Air Plants".

The Amazon: an endangered forest

We have heard a global clamor for quite a long time about the Amazon forest being devastated, as was the Atlantic forest, which started during the first years of the European presence on the continent. Not that the uproar is a negative point, it is somehow refreshing since the Amazon is vital for the climate balance both in Brazil and globally.

We have seen what has happened after the colonizers knocked down the Atlantic forest in Brazil which continued until the last decade of the 20'th century. The expansion of sugarcane created an almost desert like land in the northeast of Brazil, with soil salinization in parts where once forests existed. Rivers have disappeared and the dried out basins have formed a sterile land of what in the past was covered with life. Such will eventually happen to the Amazon, taking away the plants, trees, all kinds of life.

The Amazon forest is not only vital to the many animals, plants and insects that are endemic to the region, not to mention the humans that live there. It is immensely important for the health of the planet earth, and although it is almost totally ignored in the most important urban centers of the country, it should be a matter of concern for all people living in Brazil and the rest of the world.

The Alagoas Curassow

Long before Europeans arrived in the Americas there was a large bird which foraged in the grassy marshlands and meadows, near the forests of the Alagoas and Pernambuco states of Brazil. The bird was beautiful, about the size of a small turkey. It had bluish black feathers with a big thick red beak. The feathers on the top of it's head formed a crest which was shown at times of fear or nervousness. The crest made it the king of the birds in that restricted forest area above the San Francisco river.

It was called Mitu by the native people in Brazil, today, we call it the Alagoas Curassow. It's call was short and low, almost like a cough, which made it hard to be heard and located. The bird was described by the German naturalist Georg Marcgraf in his book Historia Naturalis Brasiliae, published in Latin in 1648, the first important scientific work in Brazil. Marcgraf was brought to Brazil by Prince Mauritz von Nassau (1604-1679) who was Governor-general of the Dutch colony in Pernambuco. After being described by Marcgraf the Mitu Mitu seems to have dropped out of sight for about 300 years, putting in doubt the identification made by the scientist. In fact, the bird was probably hiding, since it is one of the most timid birds in the Brazilian fauna. In 1951 a Brazilian ornithologist, Olivério Pinto, rediscovered Mitu Mitu hiding in the forests of Alagoas.

Climate Change - Where are they?

Sugar replacing pasture in Sao Paulo state

We are not what are probably considered to be ‘experienced’ birders. We have only been at it since 2004, but we have noticed recently that many species that were frequent visitors to our home and favorite birding sites can no longer be seen at these spots.

This southern hemisphere summer, drawing to a close now, has had unusual weather. The month of January was the wettest in recent history with over 440mm of rain, where the historical average is 267mm. As of the 10th of March, the average daily highs have been 2.2oC over normal and the average daily lows nearly 1oC above normal. There was a scant 1mm of rain when, on average, about 53 would be normal. Taken out of context these data might not be significant, but when you consider the recent convergence of scientific opinion on climate change they seem to indicate something.
