Stress hormones link food availability and population processes in seabirds (2007, background): “It takes at least 3 min for levels of CORT to begin to rise in the blood in response to a stressor (Romero & Reed 2005) so this first sample provides a baseline measure of circulating CORT and does not reflect the stress induced by capture.”
What are you actually measuring? A review of techniques that integrate the stress response on distinct time‐scales (2020, background): “Upon acute stimulation, Cort becomes upregulated within 2–5 min, depending on the species (Romero & Reed, 2005).”
Stress, corticosterone responses and avian personalities (2007, background): “exposure to a stressor (Dawson and Howe 1983; Romero and Reed 2005).”
Food availability and population processes: severity of nutritional stress during reproduction predicts survival of long‐lived seabirds (2010, background): “In general for birds, it takes at least 3 min for levels of CORT to begin to rise in the blood in response to capture (reviewed in Romero & Reed 2005).”
Short- and long-term effects of developmental corticosterone exposure on avian physiology, behavioral phenotype, cognition, and fitness: A review (2011, neutral): “Although this time-course may not hold for all taxa, it is typical for the avian species that have been examined (see Romero and Romero, 2002; Romero and Reed, 2005; Schoech et al., 1991).”
How does corticosterone affect parental behaviour and reproductive success? A study of prolactin in black-legged kittiwakes (2009, methodology): “Since blood samples were collected within 3 min of capture, the corticosterone and prolactin levels were considered to reflect baseline levels (Romero & Reed 2005; Chastel et al. 2005).”
Age and the timing of breeding in a long‐lived bird: a role for stress hormones? (2010, methodology): “For nine of them, bleeding time exceeded the time required for baseline corticosterone levels (Romero & Reed 2005), so these nine values were not used for the analysis.”
Measuring stress in wildlife: techniques for quantifying glucocorticoids (2011, background): “There are now numerous wildlife studies showing that plasma GC levels increase significantly after 2–5 min from capture (e.g., Boonstra and Singleton 1993; Cash et al. 1997; Place and Kenagy 2000; Boonstra et al. 2001; Romero and Reed 2005; Mueller et al. 2006; Wada et al. 2007; Romero et al. 2008).”
Corticosterone mediates the condition-dependent component of melanin-based coloration (2008, positive): “An increase in circulating corticosterone after an initial stress is detected after 3 min (Romero & Reed 2005; B. Almasi, unpublished data).”
Age, experience and reproductive performance in a long-lived bird: a hormonal perspective (2007, background): “As blood samples had been collected within 3 min of capture, the corticosterone levels were considered to reflect baseline levels (Wingfield et al. 1982; Kitaysky et al. 1999; Romero and Reed 2005).”
The use of glucocorticoid hormones or leucocyte profiles to measure stress in vertebrates: What’s the difference? (2018, background): “This lack of correlation at first seems paradoxical, and has sometimes been interpreted to mean one approach must be more biologically meaningful than the other (Romero & Wingfield, 2016).”
The use of leukocyte profiles to measure stress in vertebrates: a review for ecologists (2008, background): “The exact timing of the rise is not known precisely in most species; however, the existing literature demonstrates that it typically occurs within 5 min and can begin in as soon as 2 min after capture in birds (Romero & Romero 2002; Romero & Reed 2005).”
