Our last morning in Madera Canyon yesterday did not disappoint. This is a Rivoli’s Hummingbird keeping an eye on the more aggressive and smaller Broad-billed Hummingbird that was on the attack from above. Although the Rivoli’s is the second largest hummingbird in North America at a comparatively massive five inches in length, the much smaller Broad-billed Hummingbird —it is twenty-five percent smaller than the Rivoli’s—dominated the feeders. The Rivoli’s were intimidated by the aggressive Broad-bills and although I did see the Rivoli’s occasionally fighting back, for the most part, they conceded to the smaller hummer and moved away.
