trance, overhanging, well protected 

 from rain. We never collected these 

 eggs but spent quite a while watching 

 the Wren. — "From Note Book Notes,"

EARLY NESTING OF COLAPTES 

 AURATUS LUTENS IN PHILA- 

 DELPHIA, PA. 



The average nesting period for the 

 Flicker in Philadelphia, is May 10, ac- 

 cording to my data, and nests contain- 

 ing full sets earlier are a rarity. My 

 earliest records are May 10, 1006, 

 Torresdale, Philadelphia, nine half in- 

 cubated eggs, and May 16, 1917. Fish 

 House, Camden, N. J., eight hatching 

 eggs. However, on May 7, 1910, at 

 Harrowgate, Philadelphia, my brother 

 William examined a nest containing 

 eight new-born young; it was a last 

 year's hole, 30 feet up in a big, soli- 

 tary half-dead buttonwood stub, in a 

 field. This set was complete about 

 April 27, allowing eleven days for in- 

 cubation, and the first egg was laid on 

 April 20, as the Wocup lays an egg 

 daily.

LATE NESTING OF THE YELLOW- 

 BILLED CUCKOO IN PHILA- 

 DELPHIA, PA. 



On August 29, 1910, at Frankford, 

 Philadelphia, I found a Yellow-billed 

 Cuckoo's nest containing three eggs in- 

 cubation fresh and traces of blood (in 

 two). It was an old last year's nest 

 repaired, and was situated five feet up 

 in a greenbrier-covered red maple 

 sprout seven feet high, in a bushy cor- 

 ner of a large woods. The nest was 

 typical. Allowing twelve days for in- 

 cubation the eggs would have hatched 

 on about September 10, the nestlings 



would have lived seven or eight days 

 in the nest and would require at least 

 three or more days parental care be- 

 fore being able for flight, not being 

 able, probably, to care for themselves 

 before September 20, a remarkably 

 late date, as Cuckoo usually leave this 

 region in late September and early Oc- 

 tober. 



My next latest record is August 12, 

 1910, a nest of two fresh eggs in the 

 lower end of this woods and presumab- 

 ly that of the alms bird, an earlier 

 nest.

NORTH AMERICAN MIGRANTS 



SEEN DURING A WINTER IN 



PORTO RICO 



By Stuart T. Danforth 



The following observations were 

 made between Oct. 8, 1921 and June 

 30, 1922, on the western end of Porto 

 Rico, mostly around Mayaguez. Most 

 of the Ducks were seen at some la- 

 goons near Lajas, in the southwest 

 corner of the island. All of the birds 

 observed were listed by Wetmore* ex- 

 cept the Yellow-throated Warbler, 

 though I have additional data on sev- 

 eral species about which he had little 

 date. My records are lacking chiefly in 

 shore-birds, which in some cases I had 

 difficulty in identifying, as I was do- 

 ing no collecting. 



I have not included in this list such 

 forms as the Gulls, Terns, Pelicans, 

 Herons, Black-necked Stilt, etc., which 

 are common to North America and to 

 Porto Rico, but which do not migrate 

 to Porto Rico in the winter. 



An annotated list follows: 



1. Blue-winged Teal. Abundant. Oc- 

 curs in large flocks on the lagoons. 

 Last seen April 8. Two hundred and 

 fifty were seen on that date.
