10:19-17:47 = 7.5 hours.
Iiris has been absent all this time today.
Ivo remained on the nest, flying out for very short pauses.
I remember that once Ivo was also absent for more than 7 hours, then it got dark and it was not known when he returned to the nest. The next time we saw him only in the morning at 5 o'clock. There is a post about it somewhere. Then our Irma was his couple.
And his absence was explained by the fact that there was an intruder who did not want to fly away. Ivo drove him all day and then most likely they both flew far away.
