Big Bird Hunting
This is somewhat of a different bird-hunting game. It allows you to shoot the bird targets with not a gun, but rather a bow and arrow. This means you will need to practice a little bit more before getting the hang of how to nail these birds accurately and consistently. All you will have to do is simply slick the left button of your mouse to draw back the bow, aim it at a bird which is passing by, and release. Sometimes you will get them, but sometimes not; the key thing to remember is that you have to focus as much as possible when taking aim.
One important piece of advice to keep in mind is that you do not want to shoot at any of the birds before they come into sight and have a blue bubble around them. Attempting to fire an arrow at them before they have bubble surrounding them will result in an immediate miss.
You will get a different number of points, which are displayed on the screen for your in a white circle, depending on the duck you kill and how far away it was. Basically the more difficult the kill is, the more points you are likely to get. Because you are using a manual weapon, it will take more time to get the feel of it. You won't simply be able to rapid fire at the birds, so take your time and learn how the weapon works before trying to take out as many birds as you can.
