Movement and Cover-type Selection by Fledgling Ovenbirds 
(Seiiirus aurocapilla) after Independence from Adult Care

ABSTRACT.—We used radiotelemetry to monitor 
movements and cover-type selection by independent 
lledgling Ovenbirds (Seiurits aurocapilla) at two 
managed-forest sites differing in mature-forest matrix: 
open-understory deciduous lores! and dense-uiulerstory 
mixed-deciduous-conifer forest. Ovenbirds at each site 
made one to three single-day long-distance movements: 
those movements were of similar distance at the 
deciduous site Cv = 849 ± 159 m) and the mixed- 
deciduous-conifer site (v = 1,133 2 228 m). They also 
moved similar mean daily distances within stands at the 
deciduous site (x = 101 ± 12 m) and ihe mixed- 
deciduous-conifer site (a- = 105 r 11 m). and used 
areas ol similar local vegetation density, but 
denser than that ol' their nesling habitat. Fledg¬ 
lings in the deciduous study area selected sapling- 
dominated clearcuts and forested wetlands over 
mature forest and shrub-dominated clearcuts. 
Fledglings in the mixed-deciduous-conifer study 
area generally used cover types in accordance 
with availability, and tended not to use shrub- 
dominated clearcuts. Our results suggest regener¬ 
ating clearcuts may be important areas for 
independent fledgling Ovenbirds in landscapes

that consist ol otherwise contiguous open-under- 
story mature forest, but not until saplings establish 
in those clearcuts, and not necessarily in forests 
where dense understory and naturally dense areas 
such as forested wetlands are common. Received3

Many bird species that nest in mature forest use 
other cover types during the time between nesting 
and tall migration, or the post-fledging period 
(Anders et al. 1998; Pagen et al. 2000; Marshall 
et al. 2003; Vega Rivera et al. 2003; Vitz and 
Rodewald 2006; White and Faaborg 2008; Strebv 
ct al. 2011a, b). The posi-fledging use of 
regenerating clearcuts and forested wetlands by 
mature-forest species (species that breed and nest 
primarily in mature forest) has been linked to 
denser vegetation and greater food availability in 
those cover types (Vitz and Rodewald 200T 
McDermott and Wood 2010, Streby et al. 201 la). 
Survival of fledgling Ovenbirds (Seiurits auroca¬ 
pilla) is positively associated with use of dense 
understory vegetation and woody debris (King 
et al. 2006, Streby 2010. Vitz and Rodewald 
2010), Ovenbirds from nests near sapling-domi¬ 
nated clearcuts use those stands within days of 
Hedging and experience increased survival com¬ 
pared to fledglings from nests near shrub- 
dominated clearcuts or in core mature forest
