Q1. What contributions have the authors mentioned in the paper "Breeding seasonality and primary moult parameters of euplectes species in south africa" ?
In a recent study, Ostrich et al. this paper found that the primary moult duration of the Southern Red and Yellow Bishops is relatively long, at 3.4 months.
Q2. How long does the yellow bishop take to grow?
Adult Yellow Bishops needed 2–4 weeks to grow individual primaries, while the other species moulted individual primaries more quickly.
Q3. How long does the white bishop take to moult?
They estimated duration of moult to be 110 days in Southern Red Bishops, 100 days in male Fan-tailed Widows, and 80 days for Red-collared Widows and female Fan-tailed Widows.
Q4. What is the average length of the tail of a male and female?
The mean tail lengths of male and female Long-tailed Widows are 411mm and 62mm, respectively (Hockey et al. 2005);males have larger wings than females, to compensate for the aerodynamic costs of a large tail in the male (Balmford et al. 1994).
Q5. What was the type of data used to estimate the parameters of primary moult?
The data were considered to be of ‘Type 2’ of Underhill and Zucchini (1988), because full moult scores were recorded for each bird and all birds were considered to be available for sampling throughout the moult period.
Q6. What is the average number of records for the underhill-zucchini moult?
For Long-tailed Widows, 279 moult records were available (166 records for Mpumulanga, 55 for the Free State, 53 for Gauteng, and five records from other provinces).
