RE: Merriams ??
Be in Shape .
Have loud Locators, and when you get a reply be on the bird asap, as they can move off fast.
The weather is a little better at this time , presure will be a little higher aswell.
GPS's work well for these type areas.
Good Walking boots is a good Plan.
Talk to the Locals and find what info they have on birds , these are some of the nices people in the US...
Good Luck and Take Pic's ! ...BT
