--From observations
made in 1928 (Condor, xxxII, 1930, pp. 221-239) the writer estimated that there were
possibly sixteen to twenty White-tailed Kites (Elanus leucurus mcjuscdus) in the
Santa Clara Valley, located in four areas. This day (October 30, 1931) there can-
not be more than two or three, and all too possibly none! From the four areas noted
above, Kites have definitely gone from two, their presence in the third is improbable,
and in the fourth there cannot be more than two and even these at this moment may
no longer exist.
Field work from the State College at San Jose carries competent bird observers
frequently into nearly all the country from which Kites have ever been reported or
in which Kites could possibly exist. Furthermore these observers are looking for
Kites and therefore the records here given will be mournfully accurate as evidence
of the passing of this most characterful bird from one of its last strongholds in the
west. The last record of the White-tailed Kite, as listed in the publication cited
above, was on January 25, 1930, in the Arroyo Calero, about ten miles south of San
Jose. Birding trips have been made into this Arroyo not less than six times since,
but no Kite has been observed.
The breeding ground of 1928 in the Evergreen region, a locality that had three
known nests and at least eight birds at that time, was revisted for the first time
on February 16, 1930--no Kites! The same region was visited again on April 15,
1930--again no Kites! On September 6, 1930', this region was visited yet again, with
the same result. On this occasion Mr. Earland Whaley, a relative of the owner of
the property, reported that a single Kite was observed here in 1929, but that none
was noted on the nesting grounds. Visits on several occasions in 1931 have all fur-
hisbed the same sad news--no Kites.
A prolonged and careful birding trip into the region of Loyola Corners and the
Los Altos Country Club, and the hills south of Los Altos, a region that has given Kite
records on many other occasions, failed to show an individual on March 22, 1930,
and no records have since come from there.
Two students of mine reported a White-tailed Kite flying over the San Benito
River south of Gilroy on May 2, 1930. No. records have come from there since and
personal journeys through this region have not shown Kites.
One region only remains in which Kite records have been made with reasonable
regularity. This is the valley area lying between San Jose and the Bay. Here Kites
have been recorded as follows: March 22, 1930, a single individual; May 22 to June
13, 1930, Kites frequently seen, once three individuals (reported by Alfred Kopp);
August 30, 1930, two individuals; September 9 and 14, 1930, two individuals (re-
ported by Albert Ross McDonald); Deeember 20, 1930, four individuals (reported
by Emily Smith); May 16, 1931, one individual (reported by Wallace Brierly); July
28, 1931, two individuals; October 3, 1931, one individual (reported by H. G. Hill).
These reports of 1931 undoubtedly refer to a single pair of Kites. And so, from a
possible sixteen to twenty Kites in 1928, we are forced to estimate that for the entire
valley there are now probably not more than two.
There are a few faint rays of hope. First of all, Earland Whaley tells me that
the season of 1928 was the first that Kites occupied the area where the several nests
of that year were located. They were absent from that vicinity the following year.
Can it be that Kites move about in their semi,communal breeding habits and that they
now are occupying some foothill region away from roads and observing eyes? The
hope is faint. Again that region of the Santa Cruz Mountains that lies to he south-
west of Los Altos, a region once favored by Kites, could be more thoroughly explored.
Perhaps Kites may still be there.
What has taken the Kites? Between 1928 and 1931 there can have been no marked
increase in gunners in this fully settled region. There has been no alteration of breed-
ing habitats. There is therefore no conclusive evidence, though this point of more
than passing interest should be made. The Kites have disappeared from the hills and
are persisting in the single lower valley region previously occupied by them. It would
seem that the destructive factor lies in the foothills. At the risk of reasoning that
may be but remotely circumstantial if not entirely fallacious, one may mention that
there are no squirrels to be poisoned in the lower valley, but formerly there were
many in the foothills. Can there be a relation between the poisoning of the California
ground squirrel and the passing of the White-tailed Kite?AYLE PICKWELL, Stcte
