Not sure if this topic has been touched here but I a curious what are the biggest yard list from around the country that people have ammassed. For me the definition of a yard list is any bird that i have seen from my property. I live in Staten Island, NY and in 6 years have gotten 161 species of birds in my yard with some really good ones included in there such as Cerulean Warbler 2 years in a row(this is great if you know NY City birding), Brewers Blackbird, Swainson's Hawk, Yellow-throated Warbler, Northern Sawhet Owl, Bicknells Thrush and many others. One of the things that I find so amazing is the fact that I have had more Scarlet Tanagers in my yard at one time than I have seen anywhere else, ever. I had more than 20 in view at the same time on the same day. I also had 12 Rose-breasted Grosbeaks the same day. Anyway, I live at the northern tip of the island, at the top of a wooded hill, just before you get to NY Harbor so I am in a great migration spot. It never ceases to amaze me how many things can be seen in one place if you just take the time to look up.
Could others share their list, and be sure to include where you are located, highlights and the amount of time you have been keeping the list.
