“…Altricial birds are probably limited in the number of offspring they can rear by the number of pre-fledging young they can feed (Lack 1954 Despite these suggestions nest parasitism is usually assumed to be costly to the host. Some studies have shown reduced hatchability of host eggs due to nest abandonment or inefficient incubation (Semel et al 1988;Lank et al 1990; Sorenson, in press) although other studies have failed to show a cost to the host's young (Young andTitman 1988, Eadie 1989). If such costs to the host do exist then mechanisms should have evolved to prevent parasitism.…”

Nest parasitism was detected by three methods: (1) multiple eggs laid in the same nest on a single day, (2) eggs laid before or after the host's clutch was laid, and (3) large withinclutch variances in egg size and color. It was determined that 42.4% (n = 153) of completed clutches were parasitized. Parasitic eggs were laid significantly earlier in the host's laying sequence than expected by chance: 65% of parasitic eggs were laid on the first two days of laying. Number of parasitic eggs laid, as a proportion of all eggs, did not change significantly throughout the laying period. The probability of parasitic and host eggs hatching was not significantly different from that in unparasitized nests. Hosts did not reduce their clutch size in response to parasitism, when data were controlled for initiation date, nor did they hatch any fewer of their own young for a given clutch size than unparasitized nests. Parasitized nests were found in areas with higher densities (number of neighbors within 10 m) at initiation. Parasitism in this species does not appear to be a salvage strategy and may be part of a mixed or conditional strategy. University of California Press and

“…On his return; he unobtrusively took his place behind the blind with two covered props: (a) a taxidermy bobcat (Lynx rufus; 67 · 40 · 18 cm) and (b) a brown cardboard box of similar size (68 · 27 · 31 cm). Bobcats are present in the area (Nowak 1999) and have been reported as predators of passerines and cavity nesting birds (Semel et al 1988;Delibes et al 1997). The observer waited 15 min with his entire body out of sight and then waited until both adults were outside the 12 m radius perimeter (6.6 ± 15 min, mean ± SD).…”

A sex difference in the behavioural response of nesting mountain bluebirds (Sialia currucoides) to a mounted predator

Passerine nests can benefit parental fitness, but defense against predators may be costly. Although this paradigm is well studied, no studies have been conducted on mountain bluebirds (Sialia currucoides). We observed the response of 17 bluebird pairs with nestlings to a mounted bobcat (Lynx rufus) and two controls. Bluebird pairs clearly differentiated the mounted predator and males moved closer to the bobcat than to the controls whereas females did not. This system is ideal to further refine nestdefense hypotheses.

“…Such variation may result from natural variations in food availability (Hakkarainen and Korpimäki 1994;Aparicio 1999) or food supplementation (Wiebe and Bortolotti 1995). However, unusual eggs can sometimes be found in a bird's clutch, either as a result of interspecific brood parasitism (Lowther 1993) or intraspecific brood parasitism ("egg-dumping"), e.g., in ducks (Semel et al 1988;Yom-Tov 2001;Evans et al 2002).…”

An Anomalous Northern Saw-whet Owl (<em>Aegolius acadicus</em>) Egg

An anomalously large and coloured egg was found within a clutch of the Northern Saw-whet Owl (Aegolius acadicus) in Nova Scotia; all other eggs of the clutch were within the normal size and colour range for the species. Analysis of three mitochondrial genes suggests all eggs in the clutch were laid by Northern Saw-whet Owl(s) with similar genetic make-up. This is the first report of an anomalous egg from this species, and a rare example of added pigment.
