One of the pelicans found dead along Point Sable Beach recently had bilateral fractures on its wings.
That was the finding contained in a lab report received by the EMA yesterday.
Over the weekend, the EMA collected 12 birds in varying states of decomposition, with only one suitable for necropsy.
The EMA says that bird bore wing fractures were likely caused by some form of trauma, which may have led to sepsis and/or hypovolemia and the eventual death of the bird.
It says there was also evidence that the bird still eating on or around the time of death.
The EMA also provided a timeline of sorts, showing animal death events in recent years.
