BIRDS OF THE BOSTON MOUNTAINS, ARKANSAS 
51 
about homesteads in the mountains ; vet there is little doubt that a considerable 
number yet nest in hollow limbs or tree trunks. The earliest date of arrival 
was March 26; none Avere seen after September 28. Young were on the wing 
by July 18. 
Petrochelidon lunifrons lunifrons. Cliff Swallow. A small flock was 
seen near the end of April, 1913, circling about over an orchard. 
Iridoprocne bieolor. Tree Swallow. Observed on the following dates 
only: a flock of five October 3. 1913; the next spring, a pair on April 20. 
Bombycilla cedrorum. Cedar Waxwing. This species has been reported 
to breed in northern Arkansas ; but I was unable to find it nesting, or even to 
see any birds during June, July and August. I began to notice large flocks 
as September advanced ; and from then until cold weather set in, they were 
much in evidence. Cedarbirds are very fond of pokeberries, and many of the 
birds had the plumage stained in great or lesser degree with the juice of the 
berry. The chin and throat feathers are evidently the last part of the plum- 
age of the Waxwing to be acquired after molting. Such examples as were 
taken during September and October, all had these parts scantily feathered, 
or with the new feathers yet in the sheaths. 
Lanius ludovicianus migrans. Migrant Shrike. I came upon a shrike 
May 27, 1914, as it was catching some large insect upon the ground in an open 
woodland. It was rather shy, and I was unable to obtain it ; which is some- 
what regrettable seeing that it was the only time I met Avith the species in the 
mountains. HoAvever, examples examined by the Biological Survey, secured 
by various collectors from many parts of the state, including the lowlands, 
Avere determined as migrans. So under that form I list it. 
Vireosylva olivacea. Red-eyed Vireo. By far the most abundant mem- 
ber of the group found in these mountains, and the commonest arboricole bird 
during late spring and early summer. Arriving by April 16, nest building Avas 
soon in progress, and almost completed structures were found May 8. Re- 
turned southward after the middle of September, the last loiterers being seen 
on the 22nd. 
Vireosylva philadelphica. Philadelphia Vireo. Four species of vireo in 
considerable numbers Avere observed in a single tree at the same time, on April 
30, 1914. Three or four of these individuals Avere philadelphica. They Avere 
actively hunting through the topmost foliage of the tree along with a greater 
number of flavifrons ; Avhile in the lower foliage foraged olivacea and griseus. 
An addition to the state list. 
Vireosylva gilva gilva. Warbling Vireo. While previous knowledge of 
the distribution of this vireo within the state during the nesting period Avas 
limited to the immediate vicinity of the Mississippi river, it must in reality oc- 
cur at that time over most of the state, as I found it throughout the summer 
months to the very top of the range. HoAvever, it Avas much more abundant 
in migration, especially during the autumnal transit. The extreme dates for 
arrival and departure Avere April 27 and September 9. 
Lanivireo flaAufrons. Y elloAv-throa te d Vireo. This species and the Ceru- 
lean Warbler arriAmd within a feAv days of each other; each Avas partial to the 
same character of Avoodland, and both haunted the top-most foliage of trees. 
The YelloAv-throated Vireo was common almost immediately after its initial 
appearance, which was as early as April 18 ; nidification proceeded at once,
