There is very little information on the behavior of Gould's Jewelfront. This hummingbird primarily forages in forest understory and midstory (Hilty and Brown 1986, Ridgely and Greenfield 2001a, Schulenberg et al. 2010), but also ranges up into the canopy (Parker et al. 1996, Hilty 2003). There is very little information on the species of flowering plants visited by the jewelfront. The jewelfront forages for insects both by catching them in air, and by gleaning them from foliage around small open areas, and may become particularly active in foraging for insects around mixed species flocks (Hilty 2003).
There is very little information on the territorial behavior of Gould's Jewelfront. At one site in southeastern Peru, its density was estimated to be as low as 1 individual/100 ha (Terborgh et al. 1990). It does not defend flowering plants, but forages by traplining, visiting a series of spatially isolated flowers or flower clumps (Hilty 2003). Sometimes "crashes" the territorities of smaller bodied hummingbirds (Hilty 2003).
Little information. Gould's Jewelfront presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509).
Social and interspecific behavior
Gould's Jewelfront primarily is solitary, as is typical of hummingbirds.
No documented reports of predation on Gould's Jewelfront?
