Leatherback Trust To achieve this, the Park trained former poachers as eco-tour guides. Those guides now take tourists to see nesting sea turtles. Las Baulas National Marine Park now hosts guided sea turtle tours over the entire leatherback sea turtles nesting season, spanning from October until March. The Leatherback Trust played a key role in supporting the government of Costa Rica in compensating landowners for property that was within the national park. Owners cannot build or otherwise disturb that land so it is reasonable that they receive fair compensation for the land, which then becomes part of the Park. The Leatherback Trust
Loggerhead shrike shrikes may eat or discard their bodies or else feed them to their remaining young. The oldest recorded age of a loggerhead shrike was 12 years and 6 months. Loggerhead shrike populations have been decreasing in North America since the 1960s. Reasons behind the decline remain unclear, although suggestions include habitat loss, pesticide contamination, climate change and human disturbance. The eastern loggerhead shrike ("L.l. migrans") is critically endangered in Canada, with fewer than 35 known breeding pairs in Canada. The San Clemente Island shrike, "L. l. mearnsi", is critically endangered, with a population as low as 5-10 individuals during 1983-1988.
