The next PHOWN call: repeats!2011-08-12 (135)
How often should you record repeat counts of a colony? This is entirely up to you. You can submit repeats on a daily, weekly, monthly or random basis. If you submit repeats regularly but skip some becuase you are on holiday, for instance, that does not matter - simply continue when you can. You can also send repeats once a year, eg if you go on holiday to the same place every year and there are weaver colonies.
You can save a locality in your gazetteer to make it easier and quicker to upload future repeats - see here.
Repeat counts can be viewed very easily - every PHOWN record shows the repeats (if any) at the bottom of the web page. A table lists the counts per date and shows the thumbnails for each record. For example, a Cape Weaver colony in Rondevlei Nature Reserve, Cape Town, has been monitored for a year - see here. Plotting the counts of this colony provides the graph above.
