Bob- There is no conducive evidence currently that either bird is breeding in the location. My guess is that they are an early example of post-breeding dispersal. This is supported by the fact that the chestnut-sided looked like it may have been a juvenile, or if too early in the year to be one, perhaps a female that had a failed breeding attempt. The other locations that I have seen chestnuts and when are North Point State Park- August and September, Druid Hill Park- June, and my garden near Patterson Park- May and June.
Marcia- I have the same conclusion as you do that this is very far out of breeding range for either species. As I said above, there is no supposition in my mind that they are breeding at either location. If I gave that impression initially, I'm sorry. I assume they were passing through the region after breeding/after a failed breeding attempt. I do actually have the MOS Yellow Book, but thank you very much for suggesting it anyway.

Mike,
Least Flycatcher and Chestnut-sided Warbler nesting in the city would be astounding news. As you can see from the map in the latest Breeding Bird Atlas neither species is known to nest anywhere near Baltimore. For the record it would be great to have some photos or recordings, at least some written documentation for the file. You also mention that the warbler is at nearby sites. Could you provide some additional information on those please? What evidence is there for confirmation of breeding? Sometimes birds hang around in summer outside their known range and are not breeders. I would appreciate all the information you can provide because this would be a major extension of the breeding range in the state. Thank you for your help.

Today I surveyed some small wooded lots in northern Baltimore City for a community that is interested in preserving the land for use as a mini-bird-and-butterfly sanctuary. I had heard from residents that they had seen many birds in the area but didn't recognize most of them. Luckily, they made quite a show for us today, and I ended up with 18 or so birds at each location.

Both areas are off 43rd St beyond Baltimore City College High School. I will be happy to provide anyone interested with better directions. Both lots are private property, however Ms. Maybell and Mr. Cornelius Allen Red Deer welcomed me and have said that any other birders interested in seeing the lot are more than welcome. However, please remember that it is a residential area and so anyone visiting must be on their best behavior.
Good birding!
