Short-Term Alterations in Songbird Breeding Schedule Lead to Better Synchronization With Food Availability

Abstract: Resumen.-Las aves pueden, hasta cierto punto, retrasar la eclosión una vez comenzada la puesta a fin de sincronizar la fecha de eclosión con el pico de disponibilidad de alimento bien sea incrementado el intervalo de puesta entre un huevo y el siguiente o posponiendo el comienzo de la incubación. Sin embargo, los retrasos en la eclosión también pueden ser el resultado de costes energéticos ligados a las fases tempranas de la reproducción. En el presente estudio, nosotros ahondamos en el fenómeno de los retraso… Show more

“…Nestboxes were distributed in oak Quercus spp.-dominated forests and mounted on tree trunks at a height of 1.5-2.0 m (see García-Navas & Sanz [2011b] for more details on the study area). From early April to late June, nestboxes were checked as often as necessary to record first-egg date (1 ¼ 1 April), clutch size, hatching date and number of fledglings.…”

“…In all calculations, the mean laying dates were expressed as days from 1 March. Following Perrins and McCleery (1989) and Glądalski et al (2014), we calculated mid-laying-early-incubating warmth sums (mid-laying temperatures are crucial for hatching delays; García-Navas and Sanz 2011; Cresswell and McCleery 2003), as the sum of the mean daily temperatures for the 7 days starting on the 4th day since the first egg date (first egg date + 4), to characterize thermal conditions during egg laying.

“…Delaying female interrupts the laying sequence of one egg each day for three times, thus showing three laying gaps of one day of length each. This is likely conservative as mean length of laying gaps was reported to be two days in blue tits (García‐Navas and Sanz ), and laying gaps of 6 and 5 d of duration have been described in this species (García‐Navas and Sanz ) and in the closely related great tit (Cresswell and McCleery ), respectively. Because birds lay no more than one egg daily, the only strategy available to the advancing female is to show no laying gaps.…”

“…However, what (most) birds need to time with the seasonal peak of food availability is the moment of maximum food demand of their nestlings (van Noordwijk et al , Both et al ), which is more tightly related with hatching date than with laying date. After initiating egg laying, birds still have some opportunities to adjust the time of highest food demand (Cresswell and McCleery , Both and Visser , García‐Navas and Sanz , Kluen et al ), as during the several days elapsed between laying of the first egg until hatching, more precise cues will become available to birds in order to make a more accurate match with food availability.…”
