Violet-green Swallow (Tachycineta thalassina)

Habitat quality and nest-box occupancy by five species of oak woodland birds

“…Although few directly comparable studies exist, our results generally agree with those of previous studies of Ash-throated Flycatchers (Cardiff and Dittmann 2002), House Wrens (Lawler et al 2004, Johnson 2014, Oak Titmice (Wilson 1992), Violet-green Swallows (Brown et al 2011), and Western Bluebirds (Garrett and Dunn 1981, Dickinson and McGowan 2005). However, our results differed from some previous work for some species.…”

“…Violet-green Swallows are migratory aerial insectivores that breed in woodlands throughout western North America, including open deciduous woodland (Brown et al 2011). Almost no information is available on Violet-green Swallows' habitat selection, although they are known to nest in natural cavities, cliffs, and nest boxes and prefer nest sites in open areas such as in open groves or along woodland edges (Brown et al 2011). Clutch size ranges from 4 to 6 eggs (Brown et al 2011).…”

Burrowing Owl Diet at a Migratory Stopover Site and Wintering Ground on Southeast Farallon Island, California

“…Violet-green swallows feed 17 exclusively on flying insects (Brown et al 1992). Based on their feeding habits the duration of 18 risk for these swallows would be for the medium-term, the toxicant sensitivity would be low, and 19 the toxicant exposure risk is low due to the range of secondary toxicant exposure pathways.…”

Experimental brood enlargement differentially influences the magnitude of the corticosterone stress response in closely related, co‐occurring songbirds

“…Our work took place during May–August in 2015–2016 within the vicinity of Corvallis, Oregon (44.6° N, 123.3° W; elevation 70 m), where both study species initiate nests in early May and overlap for the majority of each breeding season (J. W. Rivers, unpublished data). Both swallows exhibit female‐only incubation, and have similar clutch sizes (4–7 eggs), incubation periods (13–15 days) and nestling periods (18–24 days; Brown, Knott, & Damrose, ; Winkler et al., ). Furthermore, they overlap in their foraging areas and generally feed similar food items to offspring in our study area during the period of nestling development (Garlick, Newberry, & Rivers, ).…”
