Black Headed Cardinal each day comes to the pond to feed fish. Bird red cardinal flies in for a pond up to six times a day to feed the Koi. Some zoologists suggest that this is due to the fact that the open mouths of the fish resemble the Chicks in the nest and cause the instinctive desire to feed them.
It all depends on what will bring in and how many in the nest birds. After all, the cardinal lays 5 to 15 eggs in the clutch. Here’s a protective mother, patient earn, and as voracious kids. True love, which lasts for two weeks twice a year. But the cardinal thinks his kids are still not grown.
So it will keep doing this for a long-long time.
