Details are constantly changing, but this is the information as of May 18, 2021.

When?  August 14, 2021 

Summer Wings is an annual festival (that wasn’t able to happen last year!) that highlights the birds, bats, dragonflies and other winged creatures found at the Rio Grande Nature Center. 

BioBlitz walks in which participants look for and list as many species as possible of birds, mammals, insects and plants provide opportunities for Citizen Science.  There will also be nature and bird walks, exploration of the macro-invertebrates at the Discovery Pond, and  educational arts and crafts.

Wild Life Rescue will be on-site with some of their rescued birds. And of course the Nature Shop will be open!

A Turtle in the News

From Bosque Tracks, Winter, 2021

The Nature Center’s painted turtle, Chrysemys picta, is a native species that may encounter reproduction problems from increasingly warmer temperatures and sharp temperature swings introduced by climate change. Like a number of turtle species, along with crocodilians, some lizards, and the tuatara, painted turtle embryos undergo temperature-dependent sex determination during development inside the egg. Warmer temperatures tend to produce females while cooler readings bring forth males.

Researchers at Iowa State University exposed C. picta eggs to temperature fluctuations mimicking conditions in nature as well as to conditions where oscillations were exaggerated to mimic climate change scenarios. While higher temperatures continued to produce females, cooler temperatures, expected to produce males, under the influence of intensive heat fluctuations, also produced females. Embryos from warmer profiles remained female or died when the fluctuations intensified.

“The greater temperature oscillations associated with climate change add to the effect of just higher average temperatures,” noted the research director Nicole Valenzuela. “If an average increase in temperature is accompanied by greater variance, we’ll see populations becoming unisexual faster than anticipated. The greater oscillations add to the effect of just higher average temperature.” Valenzuela said the loss of habitat and exploitation has already left many turtles vulnerable to extinction, and climate change only adds to the peril these species face.
