Question: what does a barn swallow egg look like

title: Barn swallow
text: There are normally two broods , with the original nest being reused for the second brood and being repaired and reused in subsequent years . The female lays two to seven , but typically four or five , reddish - spotted white eggs . The clutch size is influenced by latitude , with clutch sizes of northern populations being higher on average than southern populations . The eggs are 20 mm × 14 mm ( 0.79 in × 0.55 in ) in size , and weigh 1.9 g ( 0.067 oz ) , of which 5 % is shell . In Europe , the female does almost all the incubation , but in North America the male may incubate up to 25 % of the time . The incubation period is normally 14 -- 19 days , with another 18 -- 23 days before the altricial chicks fledge . The fledged young stay with , and are fed by , the parents for about a week after leaving the nest . Occasionally , first - year birds from the first brood will assist in feeding the second brood . Compared to those from early broods , juvenile barn swallows from late broods have been found to migrate at a younger age , fuel less efficiently during migration and have lower return rates the following year .
