Seabirds can get caught in fishing nets primarily because they often try to feed on the fish that are trapped in the nets. When fish are caught, seabirds may dive or reach into the nets to get to the fish, which can lead to entanglement. Additionally, in some fishing practices, bait may be used to lure fish, which can also attract seabirds that might then become entangled in the gear.
However, the most common scenario regarding hooks is related to longline fishing, where seabirds can mistake the baited hooks for food and get caught.
So the correct option related to nets would be: The birds try to eat the fish that are caught in the net.
