From: Flexible parental care: Uniparental incubation in biparentally incubating shorebirds
Example of a uniparental incubation rhythm by a biparental and a uniparental shorebird. (a) Biparental shorebird (western sandpiper) with a switch from biparental incubation (days marked green, 
) to uniparental male-only incubation (grey, 
). (b) Uniparental species (red-necked phalarope) with male-only incubation. (a,b) Pink (
) indicates nest temperatures, considered as no incubation; yellow (
) indicates nest temperatures considered as incubation while the female was on the nest and dark-blue (
) indicates when the male was on the nest (see Methods for details). Light-blue (
) indicates surface temperature in the vicinity of the nest. Temperatures were recorded every 5 s. Daily nest attendance is defined as the percentage of incubation readings (yellow + dark-blue; 
+ 
) from all nest temperature readings for that day (pink + yellow + dark-blue; 
+ 
+ 
).
