Confusion Species - Lineated Woodpecker

Carpintero real barbirrayado [Lineated Woodpecker] (Dryocopus lineatus lineatus) (♂), originally uploaded by barloventomagico.

The Lineated Woodpecker (Dryocopus lineatus), a relative of the Pileated Woodpecker (Dryocopus pileatus), is often confused with the Crimson-crested Woodpecker, and vice versa. But by comparing this picture with those of the Crimson-crested Woodpecker, the differences do become obvious. The red mustache and full red crest of this bird tells us it's a male.  Creative Commons licensed photo.

Magellanic Woodpecker - The Laughing Call

Magellanic Woodpecker, originally uploaded by billy3001.

Soon after we spotted the group of 3 birds, they spotted us. Then one of the two females flew right over to us, landing high up in the closest tree. She looked down at us and gave out a loud call that sounded as if she was laughing hysterically.  I've watched Pileated Woodpeckers (Dryocopus pileatus) often in the US, and I've yet to see any of them exhibit such bold curiosity as this bird did.
