HAB. Europe; accidental in Greenland and the Bermudas; Aleutian Islands. HABITS. The famed Skylark of the Old World can rest a twofold claim to be included in a complete list of North American birds. One of these is their occasional occurrence in the Bermudas, and in Greenland. The other is their probably successful introduction near New York. A few years since an attempt was made to introduce these birds, for which purpose several individuals were set at liberty on Long Island. For a short time they did well, and succeeded in raising one or more broods, but, owing probably to the constant persecution of all small birds by the foreign population of the neighborhood, the experiment nearly failed, and none were noticed in that vicinity. Within the last year or two, however, several pairs of these birds have been observed in Westchester County, and also on Long Island, by parties competent to recognize them, and hopes are now entertained that these desirable birds have obtained a foothold in this country.
