Las Vegas, NV (KTNV) -- The ponds at Floyd Lamb Park are a desert oasis for birds, but just last week, three geese were found dead.
Fisherman, Tom O'Leary, took one out of the pond.
"He was definitely pretty sick," O'Leary said. "He couldn't get his head out of the water and he was drowning."
Animal control is now testing dead geese, according to a city spokesperson. This comes just months after tests were also ran on more than a dozen dead ducks.
Bird lover, Tina Bauer, comes to the park weekly to care for the animals and wants to know why the parks wildlife keeps dying off.
"They picked up one Canadian Goose and two domestic geese," Bower said of animal control. "It's very unusual for them just to die like that."
Bauer hopes testing on the geese will reveal a cause of death. In July, tests on the ducks came back inconclusive. Until those results were in, the city closed the ponds to fisherman for weeks.
"I don't think it's the water," O'Leary said. "I think it's just food that their finding left out that's spoiled."
O'Leary admits sometimes fisherman leave out old bait.
Bauer feeds the geese a grain diet and hopes others will respect the park's wildlife.
"This is a historical park," Bauer said. "It belongs to migratory birds and they need serenity and peace to come here and rest and breathe and to enjoy life."
The city is still awaiting test results on the dead geese.
