Albino whitetails. Because albino is a recessive trait, inbreeding increases the frequency. Since LI is so congested with deer there is a fair amount of inbreeding and seeing albino's is not that uncommon. Always cool to see though.
I saw a white speckle combo deer out near Grumman. brown from just behind his shoulders to the tail and white and grey speckles forward. weirdest thing I ever saw. Thought it was a zombie deer.
Truth be told, I also thought I saw an anteater near the same area. it was in low grass, about the size of a medium dog, with a long snout. First time disclosing this to the public. No, I don't drink or take drugs.
Ok, THAT was the weirest thing I ever saw, the speckled deer was 2nd.
