well if birds cant smell then it is truly a mystery that a female cardinal located a peanut 1 foot from our back yard sliding glass door , it is left for a tame grey squirrel that used to sit in my lap when she was young ... snd with the over abundance of food she is extremely *** skinny for this time fo year. she has cookies, nuts, bread, flax, etc... and still no extra fat on her. And also seems like her eye sight is not the best... she will smell around he yard and i observe its as if she does not see the peanuts well until VERY VERY close or even passes them too.
A female cardinal and her mr. set up shop near our yard too every year now for 15+ yrs and while the male was feeding from the hanging feeder she was keeping an eye out for predators from our plum tree - some 25 feet from out back door - where I had left a peanut in shell and she saw it within 3 seconds of landing in tree.
she did not see my place it there* No angles of sight. due to fense**
Birding takes my mind off stuff and it adds good life to a tuff life. It also helps me forget about my spine pain and stress. Laugh, eat, be merry. Anybody with extra $ may send me some as It will permit me to travel.
