Perhaps it's because of the strangifiers added as of late, but these suddenly became a bitch and a half to find for a decent price. 8 pages selling, most painted or low crafts.

http://backpack.tf/classifieds/search/id/51fffd14ba25360405000003 (2 listings; one with paint for 3 ref and one with a spell for 10 keys, less than a week ago there were many selling for 2.33) Scratch that, the 3 ref one sold.

Selling for 2.33+

http://www.tf2outpost.com/trade/12680605 -2.66

Can't find too many selling because people buy them so quickly, no matter the price. However, most sales and offers seem to be around 2.66.

Literally almost 80% of the birds are painted.

Most of the buyers are young, but combine that with the classifieds being empty and you can conclude that the item is high in demand right now, probably because of their strange counterparts. If the young buyers are a problem, I recommend mods keep this open for a while, just to see what happens. But you also can't ignore the mass numbers of the buyers, many are having a hard time buying for current price.

Stay classy.
