This month’s meeting of the Photography group was at the recently inaugurated market in Manaus. It is a very nice market, the construction is from the colonial times, with material brought from England and France. The crafts section was my favorite, and the most colorful one. I found some piranhas there. The fruit and veggie section had just a few stands, but with lots of different herbs, dried and fresh. We got jambu for today’s lunch, pato no tucupi.
Last weekend we went for a walk to the Bosque da Ciencia. It was a short visit but we found a beautiful beetle, a blue weevil! It is a broad-nosed weevil (Curculionidae: Entiminae) with some blue on its legs and antenna.
This weekend we went for a walk to the Reserva Duke, in the northern part of Manaus. Part of the reserve is a botanical garden (Jardim Botanico) with nice trails in the forest and new exhibition areas in the forest. I really liked the little pirarucu we saw, it was just a few months old, and about 20 cm long. I will write a post about them later on. While we were looking at the exhibit about frogs and toads, I saw a beetle on the floor. I stopped paying attention to the frogs at that point. Here’s what I saw:
I decided to take the challenge to photograph the sunset. It is a different subject from what I usually photograph. I am happy with this result. I want to try different locations around Manaus to have a different view of the bridge.
The bridge, Ponte Rio Negro, links Manaus and Iranduba, and was inaugurated less than two years ago. We have crossed it a couple of times.
Amazon or South American manatee (Trichechus inunguis) is commonly hunted for meat and oil along the Amazon River. I don’t know how people manage to find them, but they do, and it is common that little ones are left without their mothers. They also get hurt by the boats. There are programs to help manatee populations recover and to reintroduce them in some areas with support of the local people. Researchers at INPA are also working on this. This photograph was taken at the Bosque da Ciencia where some manatees are brought in for recovery.
Two weeks ago I saw a couple of Guan on the mango tree in our garden. We’ve identified them as Spix’s guan (Jacu-de-spix)
Penelope jacquacu. The one on the left was cutting leaves of maracuya and giving them to the one on the right. After a while they each rested on separate branches of the tree. It was the first time I saw them, and I haven’t seen them back since.
Since I’ve moved to the tropics, I’ve learned that there are two-toed sloths and three-toed sloths. I just recently found out that they each belong to a separate family, Megalonychidae (two-toed sloths) and Bradypodidae (three-toed sloths) and they are not closely related.
Sloths are arboreal mammals, the live up in the trees and their limbs are adpated to hang from trunks and branches where they sleep or rest for about 20 hours a day. I find it very interesting that they have to go down from the trees to poo about once a week. It’s also quite interesting that they have algae living on their fur.
There are four species within Bradypus, two of which can be found in this area, Bradypus tridactylus (pale-throated sloth) and Bradypus variegatus (brown-throated sloth). The pale-throated sloth (Bradypus tridactylus) has a more resticted range east of the Andes and south of the Orinoco River, occuring in the Guyana Shield region including northern Brazil south to the Rio Negro-Rio Solimoes region (where Manaus is located). The brown-throated sloth (Bradypus variegatus), on the other hand, can be found all the way from Honduras to northern Argentina.
A week ago, we went for a walk at Bosque da Ciencia, and we saw a sloth eating young leaves up on a tree. I’m still not sure which species we saw, the pale-throated sloth or the brown-thrated sloth. Can you help me identify it?
I went downtown Manaus last sunday to walk around the market and to see what was going on with the water level. It is so high that the streets next to the river, by the port, are completely flooded. You can see the boats on port at the level of the street. There are little bridges to cross over from one side of the street to the other. Lots of people gather around to see the phenomenon, and like me, they want to document it.
We’ve been living here in Manaus since October 2010. We missed the day where the highest temperature has been recorded (38.3°C on the shade*), as it was in September that year. Soon after we arrived, we witnessed the lowest level of the Rio Negro. The level was at registered at 13.63 m*, the lowest since the measurements started 110 years ago. Last year, in August 2011, the lowest relative humidity of the past hundred years was recorded with an index of only 18%*, whereas in a hot (32.3°C) day like today we have 57% (according to our weather station). This has been recorded by my husband who maintains the weather station in our garage as well as others in the field sites where he’s working.

I’ve started sketching insects from the garden, here are a few.
We have a few floating plants in the garden pond. The flowers only last for a day; they are pretty purple with a yellow spot in the middle (I will try to do a sketch with color next time there is a flower).
