I have just updated the trip reports index for several states in the Birding The Americas Trip Report Repository. The states include Colorado, Delaware, Maryland, and Kansas. All these state indices are connected to the U.S. Index page, which is:

The various trip reports include not only those hosted on the site, but links to other useful accounts hosted elsewhere on the web.
Good birding, and safe travels,
