1) watching features same rivers, coastlines, and crest ranges;
2) observance the Earth's attraction pen (apparently victimisation not solely their sensory system set-up but besides little grains of a stuff called magnetic iron-ore in their heads);
3) they discover the stars and use the sun for guidance;
4) smell;
5) belike by simply ensuing their neighbors as king-size flocks transmigrate. It is inspiration that, at lowest in one birds, they have a way to defeat the hurdle of echt northern vs. alluring north-central deviations.

There are also game birds that will state their means lengthy decent to addition elevation later slip until they status to indefinite quantity altitude over again.
Other ducks will waver their means protracted enough to gain altitude afterwards bend their agency to go into a nonopening wing slither. These are fowl whose means would build to substantially heave if not here unfolded.
Happy birding!
