Where does “peck” come from?

I need to flag an issue with this request. The etymology chain provided appears to contain circular repetitions (peep, pip, pippin repeat) and doesn't clearly lead to or support the headword "peck." Without a coherent chain showing how these forms connect to "peck," or a known meaning for "peck" to work with, I cannot write an accurate etymology sentence following your rules. Could you provide: 1. A clarified etymology chain that actually leads to "peck" 2. The known meaning of "peck" you're working from This will let me write a proper, accurate one-sentence summary.
