You should use change event.

var body = $('html, body');

$('.country-list').on("change", function () {
    // make sure, the val() is not empty:
    if($(this).val()){
        body.animate({
            scrollTop: $('#'+$(this).val()).offset().top - 63
        }, 'slow');
    }

    return false;
});
