Light conditions (position of bird in relation to shade and to direction and amount of light):	Sunny day, few clouds. Bird was seen from several directions with respect to the light.
Optical equipment:	Brunton Binoculars, Epoch 7.5x43
Distance to bird(s):	Approximately 10 ft-50 ft
Duration of observation:	2.5 hours. Most of this time was spent waiting for the bird to return to the feeder so I could observe it. The total time the bird was actually observed was probably about 1.5 minutes.
Habitat:	The observation took place at the country home of Kathie Johnson. There were other houses in the area, but not very close. The house sits on a small hill with a seven acre lake about 100 feet from the house. The grass in the vicinity of the house is mowed. There are several large trees near the house and lake. Farther from the house and lake, the area is wooded. There were two hummingbird feeders each hung from a metal post near the house and filled with red sugar water. These feeders attract many Ruby-throated hummingbirds and of course they also attracted this Green-breasted Mango.
Behavior of bird:	The bird was seen approximately every 20 minutes feeding at one of the two hummingbird feeders located a few feet from the patio of the house. Most observers remained within the house and observed the bird through the sliding glass doors that looked out on the patio. For a short period of time, I sat outside these doors on the patio to be able to get better photographs. The bird would remain feeding only a few seconds while at the hummingbird feeders. It would then leave and return about 20 minutes later. It was occasionally observed perched on the branch of nearby trees when not feeding. Ruby-throated Hummingbirds did not feed at the feeders when this bird was present.
Description:	I spent most of my time photographing the bird rather than observing it through binoculars. I can’t do both at the same time. I thought it was important to get the photos because the Louisiana Bird Records Committee requires photos of first state record birds of which this apparently is one. I did observe that this was a large hummingbird easily two to three times the length of the Ruby-throated Hummingbirds that came to the feeder. I think you should look at the eleven photographs which are attached to this report and take that as my description of the bird. I have more photos than are attached, but these seem to show the important features of the bird. If you would like to have others, send me an email and I will gladly send them to you.
Voice:	My hearing is impaired, so even though, I was within 10 feet of the bird, I could not hear any vocalizations. Terry Davis said that he did hear the bird and I am sure that he will describe that to you in detail.
Similar species:	There are two other Anthracothorax species that are very similar: Green-throated Mango and the Black-throated Mango. According to my information, the females of the Black-throated Mango and the Green-breasted Mango are almost indistinguishable. This information also says that the females of the Green-throated Mango and the Black-throated Mango are almost indistinguishable. Thus, the females of the Green-breasted Mango, the Black-throated Mango and the Green-throated Mango are almost indistinguishable. I have no information on the juveniles of the Green-throated and Black-throated Mango. However, the photos that I took do seem to match the description of the juvenile Green-breasted Mango in that they show the buff feather edges on the wings and cinnamon along the edges of the white breast-belly stripe. My information also says that immature females have less extensive magenta in the outer tail feathers than adult females or immature males. I see very little magenta in the tail feathers of this individual. So, I would say that this is an immature female Green-breasted Mango, but I have not eliminated the immature birds of the other two species mentioned above because I don’t have sufficient information about them. There are also four other Anthracothorax species mainly from South America or the West Indies about which I have no information. I have not completely ruled out other similar species although the probability of observing the Green-breasted Mango is far greater than that of observing the other species of this genus. However, we don’t make identifications on probabilities.
Photographs or tape recordings obtained?	Photos taken by Jeff Trahan using a Canon EOS 20D SLR camera with a 400 mm Canon lens. The bird was about 10 to 20 feet away when I took the photos. Eleven photos are attached to this report. I have more photos than are attached, but these seem to show the important features of the bird. If you would like to have others, send me an email and I will gladly send them to you.
Previous experience with this species:	I have seen one individual in Costa Rica in 1999.
Identification aids:	a. at time of observation: None b. after observation: Birds of North America, Kaufman Field Guide to the Birds of North America, National Geographic A Guide to the Birds of Costa Rica, Gardner A Guide to the Birds of Mexico and Northern Central America, Howell and Webb Wikipedia
This description is written from:	notes made after the observation, memory
Are you positive of your identification? If not, explain:	No. I have not eliminated all similar species (see above, #17). The Bird Records Committee has the expertise to do this.
