Female Frog (Leptodactylus insularum) Leading Her School – Kristiina Hurme (2006)

January 29, 2014 at 2:23 pm / Ecological Documentaries, Evolution, Natural history, Short Observations, Video

Leptodactylus insularum is a tropical frog occuring in Colombia, Costa Rica, Panama, Trinidad and Tobago, Venezuela. In this video, a female Leptodactylus insularum pumps her abdomen in the water, and tries to lead the school towards a different area in the swamp. Females attend schools for varying amounts of time, and this is a fairly young school, which may explain why they are slow to follow her. Or perhaps they’re feeding on a great patch and don’t want to leave! […]

Evolution in Action – Campus Juncos at UCSD

October 15, 2013 at 10:31 am / Evolution, Video, Wildlife Documentaries

Researchers from Indiana University at Bloomington has produced a series of videos titled “Ordinary Extraordinary Junco” covering a curious bird species belonging to genus Junco that has colonized the campus of the University of California at San Diego. We have decided to highlight the 6th episode of the series but other episodes are available for viewing from the vimeo channel of the project. The series are designed to reach public and student audiences of all backgrounds and ages. The key […]

Phoebe Allens Cam – Nesting Hummingbird in California (offline)

August 10, 2013 at 3:02 pm / Video, webcams

Welcome to the busy and productive nest of the famous hummingbird known as Phoebe Allens from Orange County, southern California. UNFORTUNATELY, PHOEBE DISAPPEARED on APRIL 12th 2014. CHICKS were TAKEN UNDER REHABILITATION. This nestcam page is now maintained as a memorial for this most industrious hummingbird. You can watch other active webcams here. Since 2007 this nesting location has created a web-frenzy of natural history lovers from all over the world and formed a community of citizen scientists. Real-time observations […]

Brown Bears during Salmon Run in Katmai National Park – Live from Alaska

June 19, 2013 at 12:28 pm / Natural history, Video, webcams, Wildlife Documentaries

[Video streams have no sound and will be off air when it’s night time in Alaska] (Ursus arctos) are Caniform (dog-like) mammals. Except the polar bear (Ursus arctos horribilis) who is strictly a carnivore all other brown bears (Grizzly, Kodiak and Siberian brown bear) are omnivores and biologically are the same species. This means they can interbreed when species barriers gets lifted. As Arctic sea ice disappears polar bear habitat shrinks and thus they are forced to move southern latitudes […]

A Nest Building Hummingbird

May 10, 2013 at 6:59 pm / Natural history, Short Observations, Video

In this short but condensed observation you can watch a female Anna’s hummingbird (Calypte anna) construct her nest over 10 days between 18-28th January 2010 recorded in Victoria, British Colombia, Canada. She uses fluff feathers of other birds, spider webbings and cotton tissue around seeds of poplar trees as nest material. The size of the finished nest is typically about 5cm across x 4cm high. Unlike most other bird species in all hummingbirds nest construction and parental care is always […]

An Illustrated Introduction to Natural Selection & Sexual Selection – Cornell Lab of Ornithology (2013)

March 10, 2013 at 1:04 am / Evolution, Natural history, Video, Wildlife Documentaries

Cornell Bird Lab produced a series of quite informative teaching materials to provide scientific explanation for how new species have evolved (and are evolving). Evolution is not only a struggle for existence, it is also an effort to pass on genes to next generation. Modern biology has described mechanisms of evolution with fine details and this video effectively tells how natural selection works with three cartoonified traits in an island setting at the first few minutes. In many animals females […]

Tropical Migratory Freshwater Shrimps

August 30, 2012 at 7:59 pm / Short Observations, Video

These migratory shrimp were filmed in the Peje River, along the border of La Selva Biological Station in April of 2009 by aquatic ecologist Dr. Marcia Snyder. She studied them by measuring their habitat preferences, densities, growth rates and secondary production. She used capture mark recapture technique to estimate their densities and growth rates. Shrimp are largely nocturnal to avoid predators that like to eat them including otters, caiman and fish. During the day, they are often found hiding under […]

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 […]
