Arnold has
taken some photographs of Black-crowned Night Heron from the main wetland at
Abu Hadriyah that he has sent to me and kindly allowed me to use. Black-crowned
Night Heron is an uncommon migrant to most areas of Saudi Arabia but in the
Riyadh area is a common spring and autumn passage migrant passing early
February to early June and again from late July to early November and rarely as
late as December with birds now regularly breeding in the area. In the Eastern
Province it is an uncommon migrant noted more often in autumn than spring.
Juveniles occur from September through November and sometimes into February.
Spring occurrences are irregular from April to May.
