Rick, all;  

perhaps a combination of a bit of both, and also with migrants still clearly 
moving into mid-June, perhaps a bit more in the way of observers continuing to 
seek them.  On the other hand, there are very often a small batch of lingerers 
or non-breeders or just very slow-to-get-going-on birds that seem to linger in 
such a place as Central, and perhaps a number of other inner-urban parks. 

However we also tend to pay a bit less attention to these “later" birds, once 
the main (May) spring season is done, & for most observers, they have likely 
seen what species they had hopes of.  And of course, some of these species 
really are working their way south by now, such as (some) Worm-eating & (some) 
Yellow Warblers, and some Louisiana Waterthrush, but also a number of others 
whose first southbound movements can have begun, for a part of the masses that 
have been on the move - and either did or did not meet a mate to attempt 
nesting with.  There are also these species, in a place like Central, which is 
exceedingly depauperate in breeding-bird diversity (in comparison with 
similar-sized areas with a similar mix of habitats, including within N.Y. City 
in other boroughs), which may linger & could -potentially- attempt breeding, 
but are much more often than not unsuccessful - even in attracting a mate for 
nesting.  But in Cenral Park, especially, with all of its tens & tens of 
thousands of off-leash dogs, as well as the unnatural concentration of 
potential predators (avian, mammalian), and even that (fortunately ‘rare') 
human who does not respect birds in breeding season & causes harassments, and 
the many activities at almost all hours of the millions of other homo sapiens, 
it’s more of a wonder that the roughly-40 species that can & do nest in a 
Central Park are (for some, just barely) successful, at least some, some of the 
time.

Shorter answer:  first part - maybe, but not necessarily all that many more;  
2nd part, (same answer).  It is the Blackpoll for late June that stands out a 
bit more.
