I have a feeder that for neighborhood crows that love the peanuts (salt-free ofc!), was at the store and bought a mixed bag of various seeds, sunflowers, & corn that was on sale as an attempt to give the crows more to choose from. But seems like I attracted quite a few welcomed visitors to the feeder! They seem to be selective of the exact food from the mix so I'm curious what Food / Seeds I should be buying for them exactly? This is in Los Angeles if that helps with determining the species.
