Shades of meaning
Fernald has no entry of its own for cry out; he lists it under call.
Where he writes about it:
To ejaculate is to throw out brief, disconnected, but coherent utterances of joy, regret, and especially of appeal, petition, prayer; the use of such devotional utterances has received the special name of "ejaculatory prayer." To cry out is to give forth a louder and more excited utterance than in exclaiming or calling; one often exclaims with sudden joy as well as sorrow; if he cries out, it is oftener in grief or agony. — from call
One may exclaim, cry out, or ejaculate with no thought of others' presence; when he calls, it is to attract another's attention. — from call
