  Metamorphosis – Tale of a Wetland (Bryan Maltais 2012)

  July 24, 2013 at 12:08 pm / Ecological Documentaries, Video, Wildlife Documentaries

  Nature reveals its ability to heal when amphibians, reptiles, birds and plants repopulate a recently abandoned rock quarry to create a flourishing wetland in Fort Collins, Colorado. However, the scarred earth of this healing quarry causes salamanders to undergo a rare and peculiar shift in their morphology. Time-lapse sequences show seasonal changes of the wetland over one year accompanied by underwater footage of amphibians breeding and undergoing metamorphosis. Everybody is familiar with the metamorphosis of butterflies and moths. The following […]

  Sponge Bob or Sponge “Poop”

  April 14, 2013 at 10:07 am / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

  It is ironic that biologically diverse habitats are usually rather poor in nutrients. Coral reefs are one of them. Crystal clear waters of the tropical seas is a “clear” indication of nutrient poor environment. Because nutrients in the water column are scarce microscopic plants and animals (planktons) that form the basis of food webs cannot maintain high numbers and the water column remains clear. Dissolved organic carbon is a nutrient that is inedible for most organisms living in a reef. […]

  A Cannibal Caterpillar?

  April 11, 2013 at 7:27 am / Ecological Documentaries, Natural history, NatureDocumentaries.org, Short Observations, Video

  On September 22 2012, I encountered this caterpillar eating another fuzzy insect part along the White Trail of the State Botanical Garden of Georgia in Athens, GA. While the munching was going on, a familiar bully of the bushes the ground beetle (Calleida punctata) came in. The beetle harassed and eventually forced the caterpillar away from the leaf. I desperately needed help in explaining the sequence of events happening in this video. Why was the ground beetle so interested in […]

  Nesting Chestnut Mandibled Toucan (Ramphastos swainsonii)

  April 9, 2012 at 11:27 pm / Ecological Documentaries, Natural history, Short Observations, Video, Wildlife Documentaries

  Filmed and edited by by Jean and Phil Slosberg in 2010 the captured footage reflects a slice of natural history of chestnut-mandibled toucans. Slosbergs were able to record the nest preparation, parental care and nest maintenance phases from their home in Costa Rica. They note that after a successful breeding season the pair tried to nest in the same tree again in 2011 but were not successful because meliponid stingless bees have taken over the cavity. They attempted to clean […]

  Ants – Nature’s Secret Power (2006)

  January 29, 2012 at 11:23 am / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

  Ants, bees and wasps make up only 3 percent of animal diversity yet they may constitute up to 50 percent of the total animal biomass in land habitats. Bert Hölldobler is a leading entomologist (scientist who studies insects). He collaborated with ant biologist E.O. Wilson and developed the field of Sociobiology. The documentary does an excellent job introducing us observations coming from both natural and laboratory setting. First observation comes from the European red wood ants (Formica polyctena). These ants […]

  Nesting Nightjar in Camouflage

  January 16, 2012 at 11:25 pm / Ecological Documentaries, Natural history, Short Observations, Video, Wildlife Documentaries

  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 […]

  Daytime Hunting of Barred Owl (Strix varia)

  January 16, 2012 at 10:42 pm / Ecological Documentaries, Evolution, NatureDocumentaries.org, Short Observations, Video, Wildlife Documentaries

  On April 16th 2011, a barred owl glided over my head while I was filming something else along the Orange Trail of the State Botanical Garden of Georgia in Athens, GA. 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 […]
