The comparison of April 2012 and April 2013 is quite interesting in that it shows that the difference of 2 species is very much a net figure with about 30% of the species only being recorded in one year.
Of the 34 species seen in only one month I regard
- 10 as unusual (thus expected to be 'patchy' in occurence);
- 8 as waterbirds (evenly split between years);
- 5 as migrants (4 missing in 2013 - left early? harbingers of a cold Winter or just going somewhere wetter with more bugs?);and
- 4 are raptors (3 missing in 2013 -has the dry weather reduced the amount of prey?); leaving
- 7 evenly split between the years, none of which are very common and evenly split between years.
Having started to obsess about that I decided to repeat the exercise comparing March and April 2013.
8 are relatively rarely reported (no surprise again) and
4 are just 'missing'!
The 5 not reported in March were all more or less unusual birds although Shelduck have been regular on the Plain recently.
Thanks to observers from Widgiewa Rd, Hoskinstown Plain and Village, Wanna Wanna Rd, Radcliffe generally and Nummerak Close.
The only breeding record this month was a Sulphur-crested Cockatoo exploring a nesting hollow.
