Kleptoparasitism by Bald Eagles (Haliaeetus leucocephalus) as a factor in reducing Peregrine Falcon (Falco peregrinus) predation on Dunlin (Calidris alpina) wintering in British Columbia
Abstract
Kleptoparasitism, or food piracy, is common in a wide range of taxa, particularly among predators, with the larger species forcing smaller species to surrender their catch. The Bald Eagle (Haliaeetus leucocephalus) is known to rob Peregrine Falcons (Falco peregrinus) of just-caught prey. We present time series of kleptoparasitic interactions between eagles and peregrines hunting Dunlin (Calidris alpina) that were wintering at Boundary Bay in the Fraser River valley, British Columbia. In 1108 hours of observation during January, intermittently between 1994 and 2014, we recorded 667 sightings of Peregrine Falcons, including 817 attacks on Dunlin resulting in 120 captures. The population of wintering Bald Eagles in the study area increased from about 200 in 1994 to 1800 in 2014, while the rate of kleptoparasitism at the expense of peregrines increased from 0.05 to 0.20. The increase in the number of Bald Eagles coincided with a decline in January sightings of Peregrine Falcons, which suggests that some falcons may have left the study area because of interference from eagles. The decrease in Peregrine Falcon numbers can be expected to have led to reduced predation risk for Dunlins. Christmas Bird Counts conducted in the Fraser River Valley have underscored the fluctuation in eagle and peregrine numbers reported here.

Bald Eagle Kills Crow Chasing a Hawk
Abstract
I report predation of an American Crow (Corvus brachyrhyncos) by a Bald Eagle (Haliaeetus leucocephalus) in Washington state. The crow was attacked and killed while it was chasing a Red-tailed Hawk (Buteo jamaicensis). To the best of my knowledge, this is the first report of a bird of one species killing a bird of a second species that was chasing a bird of a third species.

What type of vultures share habitat with a bald eagle? It is unspecified in the article.

 Most likely a Turkey vulture as in the picture or an American black vulture. |

"Another study documented two bald eagle flyovers that drove two flocks of vultures (seven black and three turkey vultures, and nine black vultures and one turkey vulture) from carcasses." |

/\ That is right. There is no way a bald Eagle can chase off a Lappet faced vulture or Eurasian black vulture.
The Californian condor which is smaller than the Andean condor is able to fend off a golden eagle from its nest. I am sure it too can fend off a bald Eagle.
