Hope and Spring spring eternal. i'm glad the Mom returned but was still feeling bad since there's only one egg. i was thinking she maybe dropped others elsewhere while i was manhandling her home. turns out most birds lay one egg a day. i do believe the speculation that it's a robin family is correct.
On The Nest
Until they've laid a full clutch, robins allow all the eggs to stay cool so the babies don't start to develop. That's pretty smart! It means all the babies hatch close to the same time. Mother robins may start incubating their eggs during the evening after the second egg is laid, or after all the eggs are laid. They sit on the eggs for 12 to 14 days. The female usually does all the incubating. Even in good weather, she rarely leaves her eggs for more than 5 to 10 minutes at a time.
