GREBES THROUGH EUPHONIAS 
Four Least Grebes were at 2300 m on the road 
to Arroyo Guacamaya, Oax. 12 Jul (MC). 
Three Blue-footed Boobies (arranged in 
pairs) were on an offshore islet 70 km w. of 
Salinas Cruz, Oax. 17 Jul (MC). An imm. 
Masked Booby was sitting on the water just 
beyond the breakers at Puerto Arista, Chis. 17 
jul (MC). Ten Brown Pelicans were at 
Chicoasen Res., Chis. 19 Jul (HGdS, MPV). 
An imm. Cooper’s Hawk was above Teoti- 
tlan del Valle, Oax. 11 Jul (MC). A Peregrine 
Falcon was at Yagul, Oax. 11 Jul, and another 
was near Arriaga 17 Jul (MC). A probable 
Eurasian Collared-Dove was reported from 
Puerto Arista 7 Jul, which would be a first for 
Chis. (PB). A White-winged Dove in the zoca- 
lo at Valle Nacional, Oax. 25 Jul was in an 
area without previous summer records. A 
group of 4 Green Parakeets at San Cristobal 
de las Casas, Chis. 19 Jul probably involved 
escapees (HGdS). An Unspotted Saw-whet 
Owl was calling and responsive when other 
owls were quiet 19 Jul on the Dos Lagunas rd. 
near San Cristobal de las Casas (MC). An 
imm. male Amethyst- throated Hummingbird 
visited a Teotitlan del Valle, Oax. garden 25- 
30 Jun and 11-14 Jul, some distance away 
from its habitual pine-oak forest habitat (ph. 
EAM); this same garden was also visited by a 
Plain-capped Starthroat 14 Jul (ph. EAM). A 
Purple-crowned Eairy was constructing a nest 
on the road to Bonampak, Chis. 4-7 Jul (AM 
ph., JM). A female Wine-throated and 2 male 
and a female Broad-tailed Hummingbirds 
were in thistle fields in San Cristobal de las 
Casas 19 Jul (MC). A Speckled Mourner was 
discovered at Bonampak 6 Jun (ph. AM, JM). 
A White-throated Jay was seen at San Jose 
del Pacifico, Oax. 14 Jul (DS). Three to 5 
Black-throated Jays were in two mixed-species 
flocks with Steller’s Jay and Yellow-backed 
Orioles bn the Dos Lagunas rd. 19 Jul (MC). 
Dozens of Cliff Swallows were seen daily mi- 
grating eastward near Union Hidalgo, Oax. in 
mid-Jul (AM, JM, KSH). Three Sumichrast’s 
Wren territories were near Vega del Sol, Oax., 
where they are rapidly losing habitat 24 Jul 
(MC). Five Black-headed Nightingale-Thrush 
territories were in rainforest/cloudforest tran- 
sition in El Ocote reserve nw. of Tuxtla Gutier- 
rez, Chis. 20 Jul (MC). Three female or imm. 
Aztec Thrushes were near Arroyo Guacamaya 
12 Jul (MC). A female American Redstart at 
Bonampak 6 Jun was a late migrant (ph. AM, 
JM). A Louisiana Waterthrush was in a ranch 
near Tuxtla Gutierrez 21 Jul (MC). A pair of 
Hooded Yellowthroats feeding young were at 
San Jose del Pacifico 14 Jul (MC). Two singing 
male Blue Seedeaters were in El Ocote Bios- 
phere Reserve nw. of Tuxtla Gutierrez 20 Jul 
(MC). At least 2 White-vented Euphonias 
were at Bonampak 4 Jun (ph. AM, JM) — the 
first undisputed evidence of this species in 
Mexico.

2008, the photographs of Red-throated Pipit 
credited to Jorge Montejo were in fact taken

YUCATAN PENINSULA 
WATERFOWL THROUGH SWALLOWS 
An observation of several Eulvous 
Whistling-Ducks at Laguna Silvituc, Camp. 
7 Jul QC, RC, JG) extends the known distri- 
bution of this species just slightly farther to 
the southeast. Muscovy Duck is a declining 
species for which we report all sightings; one 
was photographed at a pond a just before the 
entrance to the archaeological site of Calak- 
mul. Camp. 7 Jul OC, RC, JG). Although 
American White Pelican has been reported 
previously in Jun, the report of 60 in the es- 
tuary behind Chuburna, 20 km w. of Progre- 
so, Yuc. 10 Jul was quite unusual (DB, HL, 
GT). Also uncommon was the report of 2 
Double-crested Cormorants on L. Coba 5 
Jul RC, JG); several Neotropic Cor- 
morants were nearby for comparison. The 
status of Zone-tailed Hawk on the peninsula 
is not entirely understood; it is thought to be 
a migrant, but the report of one at Celestiin 
10 Jul opens the possibility of local breeding 
OC, RC,JG). 
A Spotted Sandpiper near the ferry termi- 
nal on Cozumel L, Q. Roo 4 Jul QC, RC, JG) 
may represent the subregion’s first summer 
record. A Whimbrel at Progreso 9 Jul QC, RC, 
JG) was perhaps the same individual as seen 
there 10 Jul (DB, HL, GT). Six Marbled God- 
wits were in the Chuburna harbor w. of Pro- 
greso 10 Jul (DB, HL, GT). Another first sum- 
mer sighting included 2 Eranklin’s Gulls seen 
18 Jun at Progreso (DB). Three Lesser Black- 
backed Gulls were at Progreso 10 Jul, con- 
firming that this species may be found year- 
round in the area in small numbers (DB, HL, 
GT). A first-summer Common Tern at Ce- 
lestun with resident tern species 8 Jul OC, 
RC, JG) was rare for the season; the species is 
predominantly a transient in the subregion. 
Even stranger was an emaciated ad. Sooty 
Tern found on the road leading into the 
Calakmul Biosphere Reserve 8 Jul QC, RC, 
ph. JG); the closest colony is located 31 km 
off the s. shore of the state of Quintana Roo, 
and no unusual weather conditions account 
for the appearance of the bird there. 
A family of Common Tody-Flycatchers 
with 4 young was discovered along the road 
leading to the coastal village of Chuburna 10 
Jul (DB, HL, GT). At least 3 male Purple Mar- 
tins were identified among a flock of 10-12 
birds circling overhead and feeding on insects 
along the Vigia Chico Rd. 6 Jul QC, RC, JG). 
The observers assumed the others to be Gray- 
breasted Martins, which is a possibility, but
