The Red book of Lithuania

Lithuania post issued a set of two postage stamps featuring Pigeon and Dragonfly in the flora-fauna series.
Stock Pigeon (Columba oenas) is a member of the family of Columbidae, doves and pigeons. The Stock Pigeon constantly inhabits the Curonian Spit and Kazl? R?da forests in Lithuania. Larger colonies of these birds are distributed in the southern and eastern regions of the country – Dainava, R?dninkai, Lavorišk?s, Labanoras forests where pine trees dominate.
The Stock Pigeon generally inhabit mature pine forests and mixed forests. It nests in a naturally rotten hole in a tree. The eggs (usually 2) are laid in late April/early May. The Stock Pigeon is capable of raising 2–3 broods per season. Most of its food is vegetable.
Cutting down hollow dry trees and mature forests and abundance of pine martens pose the greatest threat to the Stock Pigeon. Since 1970, this species is listed in the Red Data Book of Lithuania, as well as the Berne Convention, Annex III.

Lesser Emperor (Anax parthenope) is a dragonfly of the family Aeshnidae.
It is found in Ignalina, Lazdijai, Mol?tai, Prienai, Trakai, Ukmerg?, Var?na, and Vilkaviškis districts in Lithuania. The Lesser Emperor usually inhabits the surrounding areas of forest lakes and ponds.
The female of the species insert their eggs into water plants’ stems. Larval development depends on water temperature and usually takes 1–2 years. The Lesser Emperor is most commonly seen from May to August. It feeds on insects.
Water pollution and recreational activities in its natural habitats are major threats to the Lesser Emperor. Since 1989, this species is under protection in Lithuania.
