Saving the rusty blackbird in North America


This video from the USA is called Red-winged Blackbirds: “The Biography of a Redwinged Blackbird”.

Another video from the USA, no lopnger on Youtube, was called Icterids (of Oklahoma). It said about itself:

From the Smithsonian Migratory Bird Center in the USA:

The decline and future recovery of the rusty blackbird along the South Atlantic Coast.

* Did you know that one of the fastest declining species in North America is the rusty blackbird? Global declines for the past 40 years are estimated to be more than 90 percent.

* Did you know that a sizable portion of the world population—most of the population that breeds in the eastern boreal forest of North American —winters in the flooded woodlands of the Carolinas and Georgia? Regional declines over the past 40 years are estimated to be more than 95 percent.

Much needs to be done to understand the decline and we hope much can still be done to protect and recover the rusty and its habitat while the species is still numerous. So…

Join us for a one-day workshop to discuss our current knowledge and begin to map out a plan for the future.

The smallest dinosaurs


This video is called BBC featured Walking with Dinosaurs show taken place at Brisbane Entertainment Centre.

From LiveScience:

The world’s most diminutive dinosaur is … a hummingbird!

Birds are just one lineage of dinosaurs that happened to survive to the present,” said Julia Clarke, a paleontologist at North Carolina State University and the North Carolina Museum of Natural Sciences.

As for the record-holder of the world’s smallest extinct dino, Clarke says there are a few candidates.

In the Gobi Desert, Clarke and teammates discovered a 2-foot-long dinosaur, Mahakala omnogovae. Similarly, a tiny, thick-headed dino called Micropachycephalosaurus was also 2 feet long.

At 15-inches-long and weighing fewer than 6 ounces, the slender runner, Parvicursor, takes the cake as the smallest non-avian, extinct dinosaur.

In Argentina, scientists made a big mistake naming Mussaurus or “mouse lizard,” for its small size. Later digs unveiled giant versions of this dinosaur! Scientists soon realized that they had first discovered fossils of a baby Mussaurus, but that the adults could weigh up to 250 pounds.

Did modern birds originate around the time of the dinosaurs’ demise, or have they been around far longer? See here. And here.
