The following video, “Three males on the perch, 3/16/2017—Lance-tailed Manakin Cam” was taped yesterday.
“The male Lance-tailed Manakin has an interesting breeding display, unusual in that it is cooperative rather than competitive. Two males perch next to each other on a bare stick and jump up and down alternately, sometimes giving short flights. Groups of birds may perform together, with a different stick for each pair of displaying males. The female builds a cup nest in a tree; two brown-mottled cream eggs are laid, and incubated entirely by the female for about 20 days.
The lance-tailed manakin has a number of calls, including a Toe-LEE-do, a curry-ho, and a frog-like buzzing croak given by displaying males. These manakins eat fruit and some insects. (Wikipedia)
“You shall take with you seven each of every clean animal, a male and his female; two each of animals that are unclean, a male and his female; also seven each of birds of the air, male and female, to keep the species alive on the face of all the earth.” (Genesis 7:2-3 NKJV)

The Manakin Cam Returns
On the small Panamanian island of Boca Brava, male Lance-tailed Manakins are beginning to compete for mates—which they do by working together. You’ll have a front row seat when you watch our live cam.
The Cornell Lab has partnered with Dr. Emily DuVal to bring this live view of manakins to your screen. She has been studying these cooperative displays since 1999, unraveling the mystery of why males form alliances and work together to woo females—even though only one male typically gets to mate.
Here’s what to look for: The live cam shows a display perch used by one pair of males, within a larger area with up to 30 “alpha” males and their partners. Throughout the day, the males perform coordinated displays featuring leaps and butterfly-like flights on the display perch. Occasionally, a brownish female stops by to watch. If she seems interested and receptive, the beta male typically leaves the area and the alpha male starts displaying on his own.
Through much of the day the perch may appear empty; but you can often hear the sweet calls of the male manakins singing a duet, trying to entice a female to check out one of their meticulously maintained display perches (they also have two other display areas off-cam). When the manakins aren’t around, other species (like this antshrike, this wren, or even this wood-rail!) may wander into the frame, and in the mornings and evenings the roaring of howler monkeys echoes through the forest.
