Sea turtle migration Studies of loggerhead and leatherback hatchlings have shown that moonlight reflected from the sea is an important visual cue in guiding movement from the beach to the sea. This navigational mechanism becomes a handicap if nesting sites are affected by artificial lighting since this can mean that hatchlings head towards the artificial lights rather than offshore towards the moonlit sea. Hence, the use of moonlight by turtle hatchings as a navigational cue can be considered an 'evolutionary trap'. Loggerhead and green turtles can detect the orbital movement of waves and use this information to swim perpendicular to the waves crests.
Loggerhead shrike wild when they'd naturally disperse from their parents. Since 2004, over 90 young have been released annually and between 2% and 6.5% of young released have successfully migrated and returned to breed in the subsequent year. Loggerhead shrike The loggerhead shrike ("Lanius ludovicianus") is a passerine bird in the family Laniidae. It is the only member of the shrike family endemic to North America; the related northern shrike ("L. borealis") occurs north of its range but also in the eastern Palearctic. It is nicknamed the butcherbird after its carnivorous tendencies, as it consumes prey such as amphibians, insects, lizards, small
