From Eekum Bookum:

"It’s the year of the bird @ Eekum Bookum. Jungle bird that is…. This Mulder design and sculpt will hold 20 fluid ozs. It’s a matte finish so it fits well in the hand which is important as you get into ounce 12…13…14… This mug will be a blue edition 1-75. (Orange version listed separately 1-75). Ready to ship now! As usual only 1 mug per person/household/etc."
