For fundraising purposes the birding circuit known as Satipo Road needed a new name. Rainforest Partnership has a hard time to market a road as a pristine area among non-birders, and the name Pampa Hermosa which has been used in the past is already in use at two other birding sites in Peru. A recent poll singled out Colibri Trail as the favorite, which makes much sense since there are 45 species of Hummingbirds recorded from this area. Colibri means Hummingbird in virtually every language except English.

Gouldian Finches occur in two morphs. Red heads or Black heads. Red-headed females prefer red-headed males – and black prefer blacks. In the small populations it is not always possible for the finches to chose their own type. When they cross the results are not good. However, a “hybrid” female will always have less viability than “hybrid” male. The stress of mating the “wrong”kind makes the Gouldian Finch able to regulate the outcome producing more male “hybrid” offspring which has better viability. Read Grrl Scientist fascinating account how the females do this.
