May 14 (cont.). 1948. May 14. Fourth Stop, Alamo Bridge - Added Black Phoebe, Thrush. Total list. 35 species. In the afternoon Mr. and Mrs. Roger Tony Pelton came and we walked up Strawberry Canyon (He wanted especially to see a Nuttall Vireo, hear the song of the Lutescent Warbler and see a male Allen Hummingbird). We did not succeed in finding the Nuttall Vireo. Wasp A Chocolat Warbler was building beyond Thruend of Morewood May 15. In this late afternoon I drove up Claremont Canyon a little way and up Scout Road without hearing a Nuttall Vireo. May 16. A Mourning Dove was near the N.W. corner of the house. J.T.A. heard it call and I reached the porch in time to hear it call and see it fly up the Canyon. A Tolius Warbler was in oak next kitchen. In the afternoon I went to Filden Part with R.T.P. for half an hour to listen for a Nuttall Vireo but heard none. A Thrush whistled it once, Cooler. May 17.
