More Nocturnal Sounds over Lytchett Bay

Well, I've had the recorder on over seven nights during September the most productive were the last nights of the month. In total 26 species were recorded many of which can be considered as local species, by that I mean I record them on every night I record.  But a handful I only record in spring or autumn or on the very odd occasion.

Moorhen, Coot, Snipe, Skylark and Dunlin I only recorded a few times, though Moorhen and Coot seem to be on the increase.  Moorhen are in the bay so might be moving around in the dark, Coot are scarce though are recorded in spring and autumn as are Snipe and the latter occasionally on winter nights.

A species that Paul Morton (BoPH) and Nick Hopper (Sound Approach) have both recorded on occasions around Poole Harbour is Golden Plover but they seem to have avoided my listening station here at Lytchett Bay.  Until now as this September I've recorded four individuals flying over and one recording (below) must of been very close or even over our Bungalow.

Below is the Spectrogram/Sonogram and recording of the Golden Plover calling as it passed over close to our Bungalow.

Autumn is all about the winter thrushes moving in from northern Europe and it's alway nice to record the first of the year, but then once the migration get fully underway I spend so much time counting all the contacts on the recording it become a little bit of a labour of love rather than enjoyment.  In saying this September recordings not only produced the first Song Thrush, Blackbird and Redwing the latter flew by on 29th at 05:00hrs in the morning, it also produced Wigeon, Snipe, and the first Skylark also on the morning of the 29th at 02:59hrs.

Below is the sonogram and recording of that first Redwing of the autumn.

I've recorded a number of animal sounds and in the autumn Sika Stag are always recorded usually a number of time throughout the night, and I've often thought I should compare the bellows to see if there are any differences.  So today I compared two as they sounded obviously different indeed the sonogram backed this up. In fact the first you hear would only bellow once every so often the second animal would always put in a series of three in a row then take a break.  It seems to me that the first may be more senior in rank maybe, so doesn't need to sound off as much? So it could be I can identify individual stags by their sound and get an idea of how many Stags are vying for the doe's in the Lytchett Bay recording area.

Below is the sonogram of the two different stags the first sound is the one I think is possibly the senior animal the second sound is usually giving in a group of three seperate calls.


Below is the recording of both stags
