Nine of the recordings are very brief and the quality varies from poor to very good. I assessed seven recording as being 'poor' - these possessed a lot of background noise and it was sometimes quite difficult to establish the sounds made by the subject and what was extraneous noise. Of the 31 'reasonable' recordings, it was always possible to establish the noise of the subject from extraneous noise. I rated only one recording as 'very good' but others came very close to that rating. The remaining 32 were of 'good' quality with little or no interference, but some had low recording levels preventing them from being rated as 'very good'.
On the whole the tape is useful and definitely worth listening to in advance of a trip to Ethiopia. The recordings of the endemics are of particular value and it is a pity that the quality of some of these is not better. Personally, I was really pleased at the quality of the Degodi Lark Mirafra degodiensis call and songs, and would have bought it for these alone, but that's another story.
