Jorge Garcia wasn’t always a bird paparazzo – in fact, he’s only been at it for a couple of years, after a gear upgrade for his job as a technologist took an unexpected turn. The fledgling interest soon hatched into a full-blown hobby.

This simple act of monitoring the presence of breeding birds at specified sites across the Chicago region is how the Bird Conservation Network has, over the course of more than 20 years, methodically amassed a data set that would be the envy of any research institution.

The lateleaf oak has confounded botanists since it was first discovered in the 1930s. Scientists have been hard-pressed to find a single surviving example in recent decades. But a new discovery, pending genetic testing by Morton Arboretum, could put the tree back on the map.

Fishermen are catching thousands of pounds a day and barely making a dent in the number of carp in waterways like the Illinois River, where it's estimated 20 million to 50 million could be harvested annually.
