    Nesting Nightjar in Camouflage

    This is an excellent footage capturing the behavior of a ground nesting nightjar. These birds are night-flying aerial insectivores active during dusk and dawn. It is almost impossible to see them during the day because of their camouflage. Nightjars are also known as goatsuckers which has no biological basis. If an intruder comes dangerously close to the nest, adults perform a well-known “broken wing” display. It is an excellent visual distraction. The bird will easily disappear soon after the intruder is at a […]

Hunting during daytime indicates that this individual has extra mouths to feed. You can hear the altruistic alarm calls of other nervous birds and rodents. The high pitched alarm call (of a chipmunk?) is particularly audible immediately before each move of the owl. I deliberately kept the scenes long […]

  • Acid Attack

    Acid Attack

    Wildflowers can build a community of allies for defence. Ants defend extrafloral nectaries (nectar produced in organs other than flowers) of a passion flower vine against herbivores. This is an example of plant-animal interaction evolved to solve at least three biological problems. [1] Extrafloral nectaries seen in this video resemble butterfly eggs.  Butterflies avoid laying their eggs on host plants if they see other eggs. This is particularly true for two species of butterflies Gulf fritillary (Agraulis vanillae) and Variegated […]
