Bird feeding question

[Raven]

Cardinals prefer to feed off the ground!!
but once they get accustomed to a new Bird feeder (location)
they'll be the last one to go at night and the first to arrive come morning

you can google any birds call as an MP3 file
or a dot wav file (.wav ) so google cardinal.wav
find yourself some chirps and whistles
and spike the punch so to speak
by playing them out the window

Once you get a few birds feeding they'll eventually
send out the
"hey we found the motherload call"
and more birds will approach your spot

doesn't matter which species as one takes "ques" off the other
so do some chickadees too

but, spreading out some seed on the ground where it would be highly visible
by birds flying over head makes a huge difference
orange rind believe it or not attracts cardinals to investigate more
