Rio San Juan - The new River of Raptors?

Left my house this morning to see a big raptor circling in the distance over the Rio San Juan.  Didn't quite look right for the commoner species, so I dashed back to get my bins and camera and drove down to explore further.

I straight away locked onto a couple of raptors - Crested Caracaras perched high up.  Great birds, but not top draw.  Next an American Kestrel mobbing the Caracaras.  Again, not bad.

Lower down in the same tree, though, was the original raptor - showing well and confirming my initial thoughts of Common Black Hawk.

Common Black Hawk

An exceptional bird for this part of Queretaro.  While there are a few plateau records, this species is primarily a bird of the slopes and lowlands - where it is commonly found along rivers and lakes.  

Things got even better when another raptor started mobbing the Black Hawk - a fine juvenile Red-shouldered Hawk.

Another rarish species here, though probably fairly regular in winter.  I've previously seen a couple at Centenario.  This species hunts along rivers and swamps.  After buzzing the Black Hawk, it perched up getting mobbed in turn by the angry American Kestrel.

My species list along the Rio San Juan is now up to 122.  These exceptional raptors go to the top of that list, alongside the likes of Broad-winged Hawk and Dickcissel.
