What does 'this' represent in the javascript below?

(Sorry, another this question in javascript.)

I have the code below, and I'm wondering what 'this' represents in the call at the end-- the Window or the Bird?

var Bird = (function () {
    Bird.name = 'Bird';

    function Bird(name) {
        this.name = name;
    }

    Bird.prototype.move = function (feet) {
        return alert(this.name + (" flew" + feet + "ft."));
    };

    return Bird;

}).call(this);

Well, assuming there is no parent scope, it is window

Call console.log(this) at first line in the anonymous function. That return the scope, window.

The window. .call(this) is not written inside the bird. It simply calls an anonymous function that happen to return "Bird" "constructor".

Probably window, because it's not in any particular context that would give this any special meaning.
