Huge Congregation of River Frogs Documented in Georgia

by Dirk Stevenson

When the accomplished Albert Hazen Wright (1879-1970), Cornell University Professor and Herpetologist, first encountered the strange tadpoles of the River Frog (Lithobates heckscheri), he knew instantly he was looking at a new species. Wright, who described the new frog in 1924, wrote of the species’ habitat”…swampy edges of rivers and streams, a truly fluviatile species” and mentioned that the polliwogs “travel in big schools as no other big tadpoles do.”

John Jensen, herpetologist with the Georgia Department of Natural Resources, and Jim Wright (no relation to Albert) just published a fascinating paper in the current issue of Herpetological Review about the River Frog. Last May, along the shores of a tributary to Muckalee Creek, Jim snapped incredible photos of a mass metamorphosis event of River Frogs—an estimated 4,000 tadpoles transformed and became froglets, congregating on nearby sand-and-mud-bars.

An adult female River Frog can lay 5,000 to 14,000 eggs in a floating surface film. The tadpoles require one to two years to develop and sometimes reach phenomenal sizes (ca. 5 inches) prior to metamorphosis…

Evening Grosbeak (Coccothraustes vespertinus)

Arguably, few birds are more tied to moths than the Evening Grosbeak. In the summer breeding season, Evening Grosbeaks feed primarily on the caterpillars of the spruce budworm, a small moth species that can be a pest of evergreens.

The grosbeaks have semi-nomadic populations that follow budworm outbreaks, with large concentrations of birds occurring in outbreak areas while the caterpillars are present, and moving on to other areas once the outbreak subsides.

Historically, Evening Grosbeaks were not found in eastern North America; their spread east is often attributed to increasing budworm outbreaks on that side of the continent. Their peak population levels in the east coincide with peak outbreak levels, in the 1970s and 1980s.

Since then, the forestry industry has worked to control the damaging spruce budworm outbreaks, and though no official studies have been completed to confirm cause-and-effect, grosbeak numbers have declined in lockstep.

Western populations of Eastern Grosbeak have also been on the decline, possibly due to budworm control by the forestry industry in the Rockies and western boreal forest. Both the spruce budworm and the Evening Grosbeak populations appear to have now stabilized, though at much lower levels than during the 70s.
