This article corrects the following:

Errors were found in table 2 [1] in the size of entrances, heat capacity of air and also in the quoted lumped conductances of hives and trees in the introduction. This led to the following amendments to the introduction and table 2. All other results and the conclusions drawn are unaffected.

Table 2.

General parameters.

item	value	source	item	value	source	item	value	source
κ Air	1.2 kJ K−1 kg−1	[58]	ρ Air	1 kg m−3	[58]	A Entrance	10 × 10−4 m2	[60]
L Sucrose	16.2 MJ kg−1	[59]	u Entrance	0.94 m s−1	[49]	C Honey	0.8	[4,45]
φ	162.5 J kg−1 m−1	[4]	L Water	2.426 MJ kg−1 @305 K	[7]

Typical values for the lumped conductance range from 1 W K⁻¹ for tree nests to 3 W K⁻¹ for man-made nests. Typical values for entrance size and fanned air velocity are 10 cm³ [4] and 1 m s⁻¹ [49]. These give an advection term of around 0.5 W K⁻¹; thus for hives we can ignore the energy in the advection caused by honey bees fanning at the entrance.
