Don't forget the Egg Birdfeeder:

But seriously, if you are committed to feeding birds:

1) Do not underestimate the amount of food birds (even the tiniest!) go through. So, while some of the designs above are gorgeous, you'd have to refill every 5 minutes...

2) You can't stop. Birds actually get dependent on the source. But if you do stop, try to taper, and stop at a time of year when food is otherwise plentiful.

Popoutz claims to be low in price, modern, easy to maintain, etc. It may be all these things, except the quality is horrible that all three different bird feeders I ordered within the first three days were broken by the handle and various places in slight wind and rain.

I am a novice and planned to give this brand a try with little upfront cost but before any birds flew to the feeders, the feeders were fallen to the ground one by one, leaving me stuck with large quality of bird food.

The design could seriously be improved. I would NOT recommend anyone buying this brand let alone agreeing that this is a top ten item!
