(The following is an update to the story found here.)

Officials now believe botulism at two Chicago ponds is making geese and ducks sick.

For several weeks, Waterfowl near McKinley Park and McGuane Park have been getting sick and some even died.

Officials first believed the birds were being poisoned, but tests now reveal they're suffering from avian botulism.

The illness causes paralysis and can result in drowning because the birds can't hold their heads out of the water.

Botulism is caused by decaying materials and thrives in stagnant water.

Some of the birds that were rescued are recovering and have been released.

Hundreds of baby sea turtles lose their lives after Hurricane Irene

Hundreds of baby sea turtles were unearthed and kept from making their journey to the ocean because of Hurricane Irene. It's not that the hurricane ravaged the real estate of Florida, but the higher waves and erosion paid a high price towards the imminent survival of the unhatched turtle eggs and the hatchlings alike.

...In Juno Beach, biologist Kelly Martin told News Channel 5 WPTV that every nest on the beach has been GPS tagged, and recorded which gives scientists an accurate assessment of the turtles that do not make it to the ocean for their most important first swim. Martin states there are 2200 active nests.

"Turtles have nested during hurricane season for as long as we have records, It's something they've adapted to,and it's something we've come to accept as normal," Martin states.

If you do find a hatchling or a sea turtle, please call the hotline at 888-404-FWCC (3922).

Florida cold snap devastated coral reefs

A 2010 cold snap in Florida caused widespread coral death in the reefs along the state's coast, a new study finds. In fact, the mortality rates from the cold were higher than in any other event on record.

"It was a major setback," said study researcher Diego Lirman, a professor of marine and atmospheric science at the University of Miami. "Centuries-old coral colonies were lost in a matter of days."

Winter temperatures in Florida that year hit record-breaking lows, driven down by cold air plunging southward from the Arctic. News organizations reported that Florida's tropical creatures struggled in the cold, including stubborn invasive species such as Burmese pythons and green iguanas.

Offshore, times were tough as well, researchers reported online Aug. 10, 2011, in the open-access journal PLoS Biology. The coral death rate shot up to 11.5 percent, compared with 0.5 percent in the previous five summers. The death rate dwarfs that of the summer of 2005, when Florida corals suffered high water temperatures and "bleached," the study found. Bleaching occurs when coral become stressed and expel the algae that help keep them alive. A few weeks of bleaching kills coral.
