Prothonotary Warbler Minnesota Conservation Summary
... The Prothonotary Warbler is the only eastern warbler that nests in tree cavities. It uses either natural or woodpecker-excavated cavities in dead snags or limbs of live trees, as well as nest boxes (Petit 1999). Trees with nest cavities average 15 to 20 cm in diameter at breast height (Kahl et al. ...

Bifrenaria
Bifrenaria, abbreviated Bif. in horticultural trade, is a genus of plant in family Orchidaceae. It contains 20 species found in Panama, Trinidad and South America. There are no known uses for them, but their abundant, and at first glance artificial, flowers, make them favorites of orchid growers.The genus can be split in two clearly distinct groups: one of highly robust plants with large flowers, that encompass the first species to be classified under the genus Bifrenaria; other of more delicate plants with smaller flowers occasionally classified as Stenocoryne or Adipe. There are two additional species that are normally classified as Bifrenaria, but which molecular analysis indicate to belong to different orchid groups entirely. One is Bifrenaria grandis which is endemic to Bolívia and which is now placed in Lacaena, and Bifrenaria steyermarkii, an inhabitant of the northern Amazon Forest, which does not have an alternative classification.
