If you are a serious birding hotshot and already ticked off most of what the lower 48 states have to offer, then you are unfortunately going to have to head to Alaska or get micro and target specific species one by one, but you probably already know that 🙂

Targeting US States with the most bird species diversity

The bird diversity map above shows us which US states have the largest variety of species. What I find interesting about this is how the coastal states seem to dominate, with the only exception being South Eastern Arizona. This is great it you want to combine a birding trip with some beach time… So, based off the species diversity map, the Texan Gulf Coast, California and Arizona are the top three hotspots with up to 250 species each. These states should be top of your destination priority if you want to make serious progress with your life list.

Targeting US States with the most endemic species

Targeting US States with ‘small-ranged’ birds

The choice of destination : Arizona
Arizona is our first birding destination of choice for two reasons. The first is due to it’s high species diversity (up to 250 species). The second is due to number (over 100) of small ranged bird species that exist in the area. So from a strategic point of view, you are likely to see a large variety of species, many of which you have little chance of seeing anywhere else in the US. Here is a list of popular birding areas in the South East Arizona:
- Boyce Thompson Arboretum State Park
- Buenos Aires National Wildlife Refuge
- Chiricahua Mountains
- Huachuca Mountains
- Humphreys Peak
