My first cover from Ukraine, and a very nice one because it's franked with 3 WWF stamps for my WWF collection. Thank you very much Anatoliy!
The animal pictured on the stamps, issued in 2007, is the Great white pelican (Pelecanus onocrotalus). Click on this link to learn more about this animal: http://www.birdlife.org/datazone/species/index.html?action=SpcHTMDetails.asp&sid=3809&m=0 (website of BirdLife International)
