Answer:
Sexual competition often occurs within complex social environments where male displays can be received by potential mates, rivals, or both at once. In brown-headed cowbirds’ breeding flocks, for example, multiple males sometimes vie directly for a single female’s attention; at other times males have opportunities to sing to females without interference. It was tested whether cowbirds vary the intensity of their signalling across contexts like these. The songs were recorded from males courting females both with and without a male competitor in sight. The recordings were now played to solitary, naïve females in sound attenuation chambers, and also to a naïve aviary-housed flock. The songs males had produced when they could see their competitors were more attractive, eliciting more copulatory postures from naïve females and more approaches from birds in the flock.

Ions are charged atoms or molecules. The plasma membrane is analogous to a capacitor, storing and separating charge. The voltage across the membrane varies from cell to cell, but a typical value is that the inside of the cell is -65 mV (millivolts) relative to the outside.
This may suggest that positive ions will flow into the cell when ion channels open, but, as mentioned in the question, the movement of ions is determined by both concentration and voltage.
This so called "electrochemical potential" can be calculated using the Nernst equation.
