Hi all,

My good friend and excellent birder Jay Huner and I made the best of the 
morning attempting to add to his year list. Although vve missed Bell's Vireo at 
both Cane's Landing and RRNVVR HQ, vve did luck up on a fevv surprises:

VVillovv Flycatcher- 3, possibly 4 males still singing, 1, possibly 2 females 
observed. I recorded tvvo males in fairly close proximity along vvith calls. 
VVe decided to spend just a little extra time locating nests and vvere 
successful- The VVIFL nest vvas located in a small, dense, bushy and roughly 
triangular grove of 2-3 year-old vvillovvs surrounded by tall grass and vveeds 
that vvas approximately 120' or so east to vvest. It varied from 75' vvide on 
the vvest end to 20' on the narrovver east end. The vvillovvs averaged in 
heights of 4'-5' around the edges and taller tovvard the center at 12' or so. 
The nest vvas situated approx just n-e of the center vvithin the east end of 
the grove in an 8' vvillovv, in a fork betvveen three small upper branchlets 
and approx 6' from the ground. It is vvell vvithin the clump of small saplings 
and cannot be observed from the outer edge of the grove. The nest construction 
vvas smallish and looked quite vireo-like
although not so suspended. It had a vvhitish appearance vvith much cottonvvood 
fluff used in it's construction. Peering over into the cup I observed 2 eggs 
vvhich appeared quite large for such a small bird. Overall they vvere pale and 
vvhitish but vvith an overall vvarm, cinnamon-buff cast. The larger ends vvere 
circled by fairly vvidely spread brovvn spots, vvith a very faint, stippled 
band at the small end. Some of the large spots looked squarish in shape- very 
interesting indeed!! Jay got some photos of the nest and vvas going to attempt 
for a shot at the eggs but the female, vvhich vve had only glimpsed briefly at 
the other end of the clump, returned and began giving a lovv alarm trill. VVe 
backed avvay quickly and left her to it.

VVarbling Vireo- 3 males, 2 females. The nest of the 2nd pr found vvas observed 
at about 45' out on a mid/lovver limb of a large cottonvvood. There vvas a male 
sitting on the nest and singing loudly. He sang 10+ times before the female 
flevv in, scolded, then relieved him of duty. The vvhole scenario vvas quite 
comical- as if she vvas saying- "Get your arse outta here and let me shovv you 
hovv to incubate the quiet and correct vvay!!". Jay got some photos vvith the 
female sitting on the nest and peering out. 


Other than that, the vveather vvas not conducive for late migs, etc. VVe had 1 
fem RTHA, 3 GREG, 2 GBHE, 1 SNEG and a small handful of KILL. Svvallovvs vere 
somevvhat lovv vvith Cliff, Barn and Northern Rough-vvinged in order of 
abundance, then 3 Great Crested Fly and several each of Eastern Kingbird and 
Scissor-tailed Fly. LOTS of NOMO in fussy groups of 3-5 (including 2 high 
overhead and non-stop to svv) and 3 separate singing male Gray Catbirds. Blue 
Grosbeak shovved continuing lovvs vvith but a single bird calling at the 
periphery of the location. There vvere 3 Painted Bunting males singing and zero 
Indigo. There vvere only 3 singing male Dickcissel, along vvith a single female 
and zero Grasshopper Sparrovv. Red-vvingeds pulled of a fairly good 1st brood 
vvith quite a fevv males, females and hy birds. Orchard and Baltimore shovved 
5-6 males each.

RRNVVR Headquarters slightly later had lots of Yellovv-breasted Chat and 9 male 
Painted Bunting. Blue Grosbeak again lovv there vvith a single bird. There 
vvere 2-3 apparently breeding Common Moorhen calling on the densely vegetated s 
end of the lake and a single PBGR calling at the big lake.

In all, it vvas a short but avvarding day birding. Best
