LNS NOTE: In a letter from B. McCaffrey to GB at LNS dated 15 November 1990, the recordist describes two series from Lanius excubitor. He states "male and female mated pair. . . then another series of shrike calls." This might refer to LNS 50044 and 50049 respectively. This letter is stored in the unedited file under the recordist's name. MJA, 20 April 2005. [The spectrogram shown in Figure 2 of BNA account appears to have come from this recording. Based on the caption of this figure, the present recording appears to contain primarily series of "enk" calls given by a female begging for food (0:15-0:17, 0:27-0:38, 0:52-1:05, 1:13-1:49), but also eight loud "bzeek" calls (0:18, 0:56, 0:58, 1:00 (2), 1:04, 1:06, 1:48), and "tu'-lip" notes said to be given by the male (1:49-1:51 (4), 1:54, 2:03). Not mentioned in BNA caption, there also appear to be series of "aak, aak, aak..." calls at 1:51-1:58, 1:59-2:00, and following the "tu'-lip" at 2:03. Quality changed from 3, 2-1 to 3-2, 2-1 - CAM - 7 September 2005]

LNS NOTE: Unbroken cut with internal recordist announcement/handling noise gain change (MJA, 20 April 2005).
