Word from the tupi language, Mantiqueira signifies “raindrop”, a junction of the terms amana (rain) and tykyra (drop). Its name reflects the importance of rain for the aquifer system of the region.
Spanning the states of Rio de Janeiro, Minas Gerais and Sao Paulo, its streams lead to the Jaguari river, Paraiba do Sul river and Grande river. Thus, it is of large importance to the supply of potable water and of energy for the populous cities of the southeast.
The massif of the Mantiqueira mountain range is around 500 kilometers long, and its highest point, localized by Pedra de Mina, between the states of Minas and Sao Paulo, reaches 2,798 meters. Due to its altitude, the temperature can reach negative degrees centigrade during the winter; during the summer, the intense and almost constant precipitation represents the epitome of the word Mantiqueira.
The Mantiqueira is located in the Brazilian Atlantic Forest biome, one of the most biodiverse and endangered ecosystems in the world. There are 891 species of birds recognized that occur in the Atlantic Forest, 213 of these are endemic to this biome.
Boa Vista Field Station
OAMa has as its headquarters the Boa Vista Field Station located in the Boa Vista Farm Private Natural Heritage Reserve (or RESERVA PARTICULAR DO PATRIMONIO NATURAL, RPPN in Portuguese), in the town of Bocaina de Minas, MG.
The building in which the Research Station occupies was constructed over 10 years by the owners with the aim of being a lodge centered around valorization and appreciation of the nature in the Mantiqueira range. The owner of the farm and Boa Vista RPPN, the environmentalist Lino Matheus de Sá Pereira, worked long and hard to plant a forest on the land that was mostly open pasture only 40 years ago.
OAMa’s headquarters is where we have our office and do our daily work. The structure offered by the Research Station is advantageous because we can receive volunteers for long-term monitoring over longer periods of time. It is with the support of this structure that we can also offer courses, receive collaborators for intensive projects and immersion, and also accommodate visitors that want to get to know and support OAMa. You can find more information about how to visit our site and stay at the Boa Vista Research Station here.
Bird banding is a method used around the world for studies where the identification of individuals is necessary. Some examples are population size estimates, survivorship, movement studies, behavior, intraspecific variation, prevalence of diseases and parasitism in birds among others.
In OAMa’s monitoring through banding, we use mist nets as a form of capture, and we always have professionals trained rigorously in the field to do the capture, marking, collection of data and liberation of the birds in a safe and ethical form. We follow the principles of health and safety of the team, health and safety of the birds and collection of quality data.

PORT is an abbreviation for porteira (meaning gate), and it is our first banding station in our long-term monitoring program. The name references the location where we set up our nets and banding table, right next to the gate on the Mata do Saua property, a small, rural family-owned farm.
The banding station is located at a little more than 1,000 meters of altitude on the edge of the division between forest, pasture, and house of the owners of the farm. The forest is a secondary forest with which around 20 years ago was being exploited for agricultural production.

BOA1, identifies the first banding station at the Boa Vista farm RPPN. We put the number after the name because we plan to establish a sequence of banding stations within two 52 hectares of RPPN forest. BOA1 is also located on the boarder of the forest, close to the OAMa research station. This forest, also a secondary forest and a little more than 1,100 meters high, is already a little older and has been regenerated for at least 40 years. We can recognize this because of the higher frequency of larger trees.
