If your birding around Salgados lagoon you need to keep watching the skies .
I picked up this Booted Eagle a long way off, Realizing it was coming my way I tucked in tight to a bush staying still ,motionless, camera in position letting the bird pass straight over my head.
Most days you can see Booted Eagle here but generally they tend to be a bit higher up on a thermal circling the area or over far side of the lagoon.
