There could be thousands of reasons.
Honestly, I don't think the pennies are doing it. There are plenty of copper bird baths out there & there isn't one thing I could find on the internet about anyone with a copper bird bath having birds dying. There is MUCH poison out there though. Aerial spraying of crops, poisons being used indiscriminately on lawns ect.... Have you ever watched while they spray that poison on lawns? They don't take any real care to keep it low to the ground or consider the wind blowing it in others yards. How about it drifting into bird baths? You bet it's possible! My husband & I were renting for 2 years recently & pest service came with the rental. The pest company told me what they apply will kill bugs for a YEAR but of course won't harm anything else. Yeh, right. And they spray it 2-3' up the sides of the house exterior as well as 2-3' out from the house on the ground. If the technician spraying it has to wear chemical proof gloves & boots then what are the birds supposed to wear?
And when it rains & that stuff runs off & gets in the puddles & wildlife drinks from those puddles what do you think happens?
My rant for today. Off my soapbox.
And I wasn't honking on you flowerpetal. And WELCOME, WELCOME, WELCOME to ATP!
