Feeding Ecology of the Blue-fronted Amazon

Category: Diet, Pantanal | Date: Jul 16 2009 | By: Blue-fronted Amazon

On the first part of my PhD dissertation, I analyzed the feeding behavior of the Blue-fronted Amazon. Once a month, from July 2005 to Dec 2007, my team and I used trails in different environments in Pantanal to observe the parrots.

I registered 1,349 Blue-fronted Amazon eating flowers, fruits, and seeds from 48 different plant species. The high seed consumption indicates that this parrot is mainly a graminivore of canopy trees. In general, the Blue-fronted Amazon is a generalist, with a very diverse diet, in response to the intense variety of resources in a seasonal and heterogeneous environment, such as Pantanal. Our next step will be to evaluate the nutritional composition of the Blue-fronted Amazon diet, with the collaboration of researches from different institutions.

12-year study of the Blue-fronted Amazon in Pantanal

Category: Award, Pantanal | Date: Jul 06 2009 | By: Blue-fronted Amazon

Hi everyone! I think I need to start apologizing for the lack of posts for the past few months… The Project continues very active, with many field trips. But I have been super busy finalizing my PhD dissertation (on Ecology and Conservation, Mato Grosso do Sul Federal University), and I did not have any time to post some news in the blog…

Well, finally, on June 22nd, I defended my dissertation, on a 12-year long study about the Blue-fronted Amazon, which is divided in three chapters: feeding ecology (3-year observation period), collective roosting sites (4-year observation period), and reproductive success (12-year observation period). Many people directly contributed to data collection, such as our field technician Vandir, several externs, biologists, veterinarians, and zootechnists, and, of course, the essential orientation of Prof. Dr. José Ragusa Netto/UFMS Três Lagoas. The material and financial support of many people and institutions was fundamental for this study. The Project continues, aiming to help the development of conservation plans for this species and its environment.

I would like to thanks everyone who direct or indirectly helped the Project, and to share with you the happiness of having concluded my PhD degree! And I promise new posts soon!!
