Re: Second Clutch Possibilities ?

Bill, I documented one such occurence in 2017, as you may have read in the earlier Forum post. I nest check religiously. Plenty of nest checks and nest replacements made it possible to verify that two full nesting cycles occurred. From the first egg in the first nest to the fledging of the young on ...

Re: Second nest?

I have only had one experience with a second nest by the same pair of martins. In 2017, I had an ASY pair lay their first egg on May 18 and fledge 3 nestlings on schedule on July 5th. On July 17, with fledglings still appearing at this nest and after wondering why this adult pair was still active in...

Re: Cresent Versus Modified Excluder Entrances?

I have both entrances and have never had a starling breach. Starlings try both early in the season, give up and never bother all season. I think that the Modified Excluder would be more difficult for even a smaller starling to enter based on their larger sternum. Others will chime in. All are occupi...

Re: I'm going to need bigger gourds- 10 nestlings in one.

Final nest completed fledging 7 nestlings this morning. Checked all gourds as it was the first time In months with all martins out flying. No dead found. 67 nestlings successfully fledged out of 67 eggs that hatched. Successful year. They should still be around for another week or ten days or so bef...

Re: The Lone Chick seems to be pulling through.

I suggest watching the nest he is in closely, if you can. If you observe adults bringing insects within a half hour or so, I would not necessarily worry. One chick does not require as many visits as a nest full. Are you saying there were two chicks in the nest yesterday? That would be a concern. A n...

Re: The Lone Chick seems to be pulling through.

This one could not have made it without you. Quality is better than quantity. One martin at a time. Fortunately, it is usually not this involved.

Good job.

Re: I'm going to need bigger gourds- 10 nestlings in one.

Just completed the last of the nest replacements on my gourds. All 67 (100%) of the nestlings that hatched were still alive and well during the last of three nest replacements. The 4 nestlings transfered from the nest of 10 nestlings all survived as did the 6 remaning in the original nest. The oldes...

Re: Had Martins again but no breeding. Looking for some advice

Google the Wisconsin Purple Martin Association and you will find some groups to contact. Realistically, it can take a long time to attract martins. Location is the most important criteria. There are quite a few martin colonies within a short drive from you. Being between Lake Michigan and Lake Winne...

Re: At what age do the babies fly out of the gourds?

It varies from as early as 26 days to 33 days at my colony. How old are your nestlings? How many do you have this year? Not all nestlings in a nest are the same age or size. Hatching can take two days and I had a nest that hatched over three days this year. One nest here began fledgling yesterday at...

Re: how many broods?

Jeff, Too late this year for nesting but you can still attract some as northern martins and this years' young begin exploring and heading south in the next 6 to 8 weeks. Over the next several weeks or months, I suggest searching thru the contents of this Forum as well as the information in the banne...

Re: Advice for 2021 improvements?

I concur with the previous advice. A housing upgrade is needed. Check out the many options available on the PMCA shop. Individual gourds or multifamily housing of quality will be less expensive in the long run. Explore your area for existing martin colonies to see what appeals to you. Keep in mind w...

Re: Martinwatch nest data sheet, fledged?

Dave, Another good question. I guess I just used an "F" to indicate fledged without really thinking about it. The list on the bottom of the sheet only gives an"X" to indicate an empty cavity. I know my yearly data has been accepted as I get my yearly magnet in return.Maybe the PMCA will respond. I d...

Re: Bad eggs?

At times, some females will lay eggs in nests other than their own. Egg dumping has been observed in over 200 species. Ducks are notorious for this, with some nests containing 30 or more eggs. I just had a nest with 10 viable eggs this year. Two eggs appeared on the same day. Obviously, one hen did ...

Re: Martinwatch nest data sheet, fledged?

Good question for a couple reasons. First is that it is required to verify fledgling for each nest by marking fledge (F) if your data is to be counted when you submit the Martinwatch data. Second is not to get too hung up on individual fledge dates as nestlings often fledge over several days. I make...

Re: Taking gourds down?

Leave them up. I bet there are martins checking them out. You cannot be there every daylight hour. If you have not prenested them, do so. It looks like they have been used previously. Ask the active colony when they lower their gourds/ house and follow their guidance.

Good luck in the future.

Re: Bad eggs?

Strange outcome. With about 23 pair of martins, even if they averaged 4 eggs a pair, you should expect about 100 eggs. 9 eggs in one nest could include sterile eggs or be a case of egg dumping. Watch when hatching is expected to see how many hatch. In had a clutch of 10 eggs this year and they all h...

Re: Bad eggs?

Early sudies by the PMCA showed a significant advantage to providing calcium, specifically oyster shells as a supplement, in that it increased egg production and chick survival. Many just use crushed egg shells. If you are not providing a source of calcium, I suggest doing so. I supply crushed oyste...

Re: Has this baby been wounded?

It looks like a wound. With the dry green leaves in the nest, it looks like the nest has not been replaced. Bird blow fly larvae may be present and have fed on the nestling causing a raw area. I suggest nest replacement to be sure none are present. I might also use a little bit of antibiotic salve b...

Re: Nest Changes ?? Or Not ??

Bill, If you are doing regular nest checks and have found no vermin and the nests are in good shape, you are in good shape to allow the nests to go as they are. I would still conduct nest checks in case any issues such as mites or buffalo gnats show up but you sound like your colony is in good shape...
