Last pix today and more to follow tomorrow
Wing of juv Turtle Dove.
Note the new adult like lesser covert with a dark feather centre.
The juv.Lesser and Median Cocerts are generally,pale rufous grey with whitish terminal fringes.
Also see that the rest of wing coverts are tipped pale rufous.
Both the birds had undergone a very limited post juv moult,both tails were moulting irregularly
The wing lengths were very interesting both very short,164 and 158 mm.,c.f. nominate race average albeit for full ground male and females with averages of 179 and 172 mm respectively.
Even the N.W.Africa and Balearic race have longer wings again albeit for adults of 175 and 167 mm respectively.
Will look up wing lengths of the 2 birds That i trapped at this same site last year and let you know how they compared,think they were juvs too.
