Righter, Keller : Bird Songs of the Rocky Mountains :

| | | Set mit 3 CD's, Booklets. | WG: Bioakustik-Produkt | Drei CD's mit Stimmen von über 250 Arten der Rocky-Mountain-Staaten. | The Rocky Mountain states and provinces offer some of the greatest birding in continental North America, and this 3-CD set captures it. We bring you vocalizations of more than 250 species found in this region, including call types not found on any other western audio guide. Listen to superb examples of Empidonax vocalizations--more call types per species, voices you have to know to make correct ID's. How about the amazing "bumblebee" sound of Callipe Hummingbird? The diagnostic rattle calls of longspurs? How about Great Gray Owl begging calls? The "agressive" song and we-o call of Lark Bunting? You won't hear these on any other CD. This is the only audio guide that pulls together characteristic sounds essential to identify the birds of this region. You won't find a better set of recordings for this purpose! | [E] | |
