Description: Based on ringing data from the Western Cape, Underhill et al.(1995) demonstrated that there was a bimodal distribution of wing-length measurements in the Lesser Honeyguide Indicator minor, and they described the timing of wing-moult in this region. Hanmer (1997) reported similar results for Lesser Honeyguides from Mozambique and Malawi. This species remains poorly studied, and we have examined size dimorphism and wing moult for a sample of birds from the Eastern Cape region: 44 museum specimens from the Albany Museum (Grahamstown), East London Museum and the Ditsong Museum (formerly Transvaal Museum, Pretoria), together with ringing data for 94 birds. Wing-length of both museum specimens and ringed birds was measured in the standard manner (maximum chord); weight to the nearest 0.5 g was recorded with a Pesola spring balance. Each bird was checked for wing moult, which was recorded as 0 for an old feather and 5 for a fully grown new feather (de Beer et al. 2001). These moult scores were converted to percentage feather mass grown using a primary feather mass index, Passer9 (Bonnevie 2010a), for analysis using the model of Underhill and Zucchini (1988), as implemented in R (Erni et al. in press), with the data subsampled to prevent non-moulting birds from biasing the estimates (Bonnevie 2010b).
